Hey, it's an organic way for the neighborhood kids to get together and have fun with the urban landscape. It's kind of like living across the road from Diamond Head in Honolulu except that the ground here is concrete and indigenous scrub brush instead of beautiful black sand and palms; and the kids are skating instead of surfing; and the temperature in January is 20 below instead of 80 and....well, never mind. Anyway, it was pretty cool to watch until the cops came and made everybody pack up their gear and go somewhere else to possibly break their necks on private property. I'm pretty sure everyone flipped them off, too.
