21. Johnson's Shut-Ins. The manmade waterworks at Raging Rivers and Six Flag's Hurricane Harbor are a lot of fun, but they're not nearly as cool and awe-inspiring as the natural chutes, eddies and waterfalls found a mere two hours south of St. Louis at Johnson's Shut-Ins State Park. (Near the intersection of MO-N and MO-mm, Lesterville; 573-546-2450)
22. Citygarden fountains. If Johnson's Shut-Ins is too far, hop on the MetroLink and head downtown to Citygarden where the dancing fountain and wading pool offer a welcome respite from the city heat. (801 Market Street; 314-241-7070)
23. Fair Saint Louis. Big-name musical acts, daily air shows and nightly fireworks. Oh, and did we mention it's all free? The weekend of July 4th, the downtown riverfront is the place to be.
24. Above-ground pools. Is there anything more St. Louis than a big metal tub in the back yard? What these pools lack in modern amenities (diving boards, chlorine) they make up for in good, old-fashioned fun. Try as you might, you'll never make a whirlpool by running around an in-ground pool.
25. Shakespeare in the Park. For three weeks each summer Forest Park hosts a free Shakespeare play under the trees just east of Art Hill. This year's play is the bard's comedy Twelfth Night. Bring some friends, pack a picnic and arrive any day but Tuesday from May 24 to June 16.
