Playing PIG is cool...
late evenings at the local park sometimes lead to a PIG session with the local whipper snappers... they usually up the ante with new school stuff while we old ones use old skool arts to quell the youthful uprising..it terrifies them when they have to attempt no foot Nose picks with their brakeless 20lb bikes...LOL
seriously it helps to push your skills and led to me throwing both hands above my head doing the local hip jump (a first) and some new wounds to impress my friends (bloody tailwhips still cant land them!!)
