A
skate park is a recreational area where
skateboarders,
inline skaters, and
bicyclists can perform tricks. Two essential components of any skate park are
halfpipes[?],
quarter pipes[?] and handrails. A skate park may also contain
trick boxes[?],
vert ramps[?], pyramids, banked ramps, full pipes, stairs, and any number of other trick-oriented objects.
