The thing with street skating, most skaters get the approach to it all wrong, they go out looking for a stair set, or looking for a ledge, or a rail, or a manny pad etc, and it has to be a certain way. It really becomes a limiting factor, sure they get great at skating those things, but theres no out of the box thinking from them.
Look at skaters like richie jackson, daewon song, chris haslam, or that japanese guy - gou miyagi. These people dont go out looking for typical stuff to work on typical tricks, they go out and look at everything and ask themselves what they can make happen. And now we have richie jackson bertsliding whilst holding onto a wet floor sign, daewons skating off boulders and trees. People like joe moore are mixing freestyle type tricks into unusual obstacles.
Point is, no matter where you are there are places to skate.
