70 Corwin St., San Francisco
The best things in life really are free and this slide-from-hell proves that. This ride is one of the biggest (legal) rushes in the Bay Area. Located in a nondescript neighborhood in between foliage, houses, and apartments, your GPS may have trouble finding this harrowing slide, but that only adds to the adventure. Bring a big piece of cardboard or a plastic dinner tray to ride and some thick pants and a long-sleeved shirt to wear. You will bail the first time so be prepared and don’t let your kids try unless they’re dressed the same. Race your buddy since there are two slides but keep your arms and feet tucked in if you like them the way they are.
