:laughing kevin, y am i not surprised that uve got a line up...
theres a park around the corner from my house w/ some sturdy volleyball poles in sand. a good soft landing and a beer or two gives us the courage to try some stupid shit, though we'll prob never try flips, jumps/spins are hard enough.
one thing i tried last week. lay down under the line and try to get on it. chin makes a good hook and the bruise on your inner thigh really starts to hurt after too many tries.
