Ravinia Festival
Want to know where the natives get away from it all? Come summertime, you'll find us chilling on the lawn at Ravinia, the summer home of the highly regarded Chicago Symphony Orchestra in suburban Highland Park. The season runs from mid-June to Labor Day and includes far more than classical concerts: You can also catch pop acts, dance performances, operatic arias, and blues concerts. Tickets are sold to both the covered pavilion, where you get a reserved seat and a view of the stage, and the lawn, which is the real joy of Ravinia: sitting under the stars and a canopy of leafy branches while listening to music and indulging in an elaborate picnic (it's a local tradition to try to outdo everyone else by bringing candelabras and fine china). I've been here for everything from Beethoven symphonies to folky singer-songwriters, and the setting has been magical every time. The lawn to the left of the stage is a popular place for families to spread out, but I'm partial to the tree-filled area on the right (the lights projected into the branches create a dramatic effect after the sun sets).Don't let the distance from downtown discourage you from visiting, because Ravinia is served by an extremely convenient public-transportation system. Any evening a concert is scheduled, a special Ravinia Metra commuter train leaves at 5:50pm from the North Western train station at Madison and Canal streets (just west of the Loop). The train stops directly at the festival at 6:30pm, plenty of time to enjoy a picnic before an 8 o'clock showtime. After the concert, trains wait right outside the gates to take commuters back to the city. The round-trip train fare is $5, a real bargain considering that traffic around the park can be brutal.Dining options available at the park range from the fine-dining restaurant Mirabelle (tel. 847/432-7550 for reservations) to prepacked picnic spreads from the Gatehouse, featuring gourmet items to go. For $10, you can rent a pair of lawn chairs and a table from booths set up near the park entrance. In case you're wondering about the weather conditions at concert time, dial Ravinia's Weather Line (tel. 847/433-5010).

Museum of Science and Industry
Even if you don't plan on spending the day in Hyde Park, you'll pass through the neighborhood on your way to one of Chicago's most popular tourist attractions. The massive Museum of Science and Industry is the granddaddy of interactive museums, with some 2,000 exhibits. You should plan on spending at least a couple of hours here, and a comprehensive visit can take all day, especially if you catch an Omnimax movie while you're here. Although it's quite a distance from the rest of Chicago's tourist attractions, it's easy enough to get here without a car; your best options are the no. 6 Jeffrey Express bus or the Metra Electric train from downtown (the no. 10 bus runs from downtown to the museum's front entrance during the summer).While the museum is constantly adding new exhibits to cover the latest scientific breakthroughs, you shouldn't miss certain tried-and-true exhibits that have been here for years and epitomize the museum for Chicagoans. The U-505, a German submarine that was captured in 1944 and brought to the museum 10 years later, brings home the claustrophobic reality of underwater naval life. The full-scale Coal Mine, which dates back to 1934, now incorporates modern mining techniques into the exhibit -- but the best part is the simulated trip down into a dark, mysterious mine. Get to these exhibits quickly after the museum opens because they attract amusement-park-length lines during the day.Kids who love planes, trains, and automobiles shouldn't miss All Aboard the Silver Streak, a refurbished Burlington Pioneer Zephyr train with on-board interactive exhibits; the massive model train exhibit that makes up The Great Train Story; or Take Flight, an aviation exhibit featuring a full-size 727 airplane that revs up its engines and replays the voice recordings from a San Francisco-Chicago flight periodically throughout the day. Computer addicts should be entranced by Networld, which offers a flashy immersion into the Internet (with plenty of interactive screens). More low-tech -- but fascinating -- is the giant walk-through model of the human heart. Well-designed educational exhibits include AIDS: The War Within (which was the first permanent museum exhibit on the immune system and HIV) and Reusable City, which teaches children ecological tips with implements that they might find in their own backyard. Older children with a creative streak will enjoy Enterprise, which lets visitors take on the role of CEO for a day as they immerse themselves in the goings-on of a virtual company.And, not to be sexist, but girls (myself included) love Colleen Moore's Fairy Castle, a lavishly decorated miniature palace filled with priceless treasures (yes, those are real diamonds and pearls in the chandeliers). The castle is hidden away on the lower level. Also tucked away in an inconspicuous spot -- along the Blue stairwell between the Main Floor and the Balcony -- are the Human Body Slices, actual slivers of human cadavers that are guaranteed to impress teenagers in search of something truly gross.A major newer addition to the museum is the Henry Crown Space Center, where the story of space exploration is documented in copious detail, highlighted by a simulated space-shuttle experience through sight and sound at the center's five-story Omnimax Theater. The theater offers double features on the weekends; call for show times.When you've worked up an appetite, you can visit one of the museum's five restaurants, including a Pizza Hut and an ice-cream parlor, and there are also two gift shops. Allow 3 hours.

John G. Shedd Aquarium
The Shedd is a city treasure and well deserving of its title as world's largest indoor aquarium. A mix of standard aquarium tanks and elaborate new habitats, this marble octagon building is filled with thousands of denizens of river, lake, and sea. The only problem with the Shedd is its steep admission price. You can keep your costs down by buying the "Aquarium Only" admission, but then you'll be missing some of the most stunning exhibits.The first thing you'll see as you enter is the Caribbean Coral Reef. This 90,000-gallon circular tank occupies the Beaux Arts-style central rotunda, entertaining spectators who press up against the glass to ogle divers feeding nurse sharks, barracudas, stingrays, and a hawksbill sea turtle. New technology includes an enhanced sound system and a roving camera connected to video monitors mounted on the tank's periphery, which gives visitors close-ups of the animals inside. It's worth sticking around to catch one of the daily feedings, when a diver swims around the tank and (thanks to a microphone) talks about the species and their eating habits.The exhibits surrounding the Caribbean coral reef re-create different marine habitats around the world. The best is Amazon Rising: Seasons of the River, a re-creation of the Amazon basin that showcases far more than fish (although you'll get to see some sharp-toothed piranhas as well).You'll pay extra to see the other Shedd highlights, but they're quite impressive, so I'd suggest shelling out for at least one. The Oceanarium , with a wall of windows revealing the lake outside, re-creates a Pacific Northwest coastal environment and creates the illusion of one uninterrupted expanse of sea. On a fixed performance schedule in a large pool flanked by an amphitheater, a crew of friendly trainers puts dolphins through their paces of leaping dives, breaches, and tail walking. Check out the Oceanarium schedule as soon as you get to the Shedd; seating space fills up quickly for the shows, so you'll want to get there early. If you're visiting during a summer weekend, you may also want to buy your Oceanarium ticket in advance to make sure you can catch a show that day. The newest signature exhibit is Wild Reef -- Sharks at Shedd , a series of 26 interconnected habitats that house a Philippine coral reef patrolled by sharks and other predators. The floor-to-ceiling windows bring those toothy swimmers up close and personal (they even swim over your head at certain spots).If you want a quality sit-down meal in a restaurant with a spectacular view of Lake Michigan, check out Soundings, right there inside the aquarium. There's also a family-friendly cafeteria. Allow 2 to 3 hours.
