So you say you still haven't checked out the Seward Street Slides? Then it's time to grab a pizza box and head out for some superlative sixth-grade fun. Back in the residential neighborhood of Eureka Valley are twin concrete shoots available for anyone's sliding pleasure. For more than 30 years, these slides have been providing cheap thrills for San Franciscans who ride down them on cardboard concoctions. Keep your hands folded across your chest, or raise them up rollercoaster-style. Make that cheap and fast thrills. The slides are short and steep so all the fun is over in about 4 seconds. Just do what you did when you were a kid: Go again. And again, and again. Some showboaters get creative, using wax paper for hyper-speed sliding. Superslick.
Avoid going to the slides at night, and be aware that it's located in a residential neighborhood. The slides are on Seward St. at Douglass St.
