thanks for the ideas guys but i already have some of the things wiltz said such as:

After earthquake (not released yet)
Art museum
Mine (not uploaded)
Docks
Ghetto
Suburbs

But i still am down for some of the others on that list such as

Rebuilding a beachside skatepark(made one before)
playground
Abandoned depot
or a water treatment plant..

But I just started a skate camp whic is turning out pretty decent at the time so once I finish that up I'll be down to try these new ideas.
