Dogtown and Z-Boys

I never surfed or skateboarded but I still found this documentary fascinating. I accidentally stumbled on it while channel surfing (not sidewalk surfing) and watched it a second time later in the day. The Z-Boys made me think of the early days of rock and roll when young kids with no formal musical training basically "invented" rock and roll as they went along.. It seems the Z-Boys did the same with skateboarding.
