Pick one. The rule of this game (my rule, anyways) is you can only guess one track at a time, otherwise, somebody could just show up and post EVERY track in the game.
I'm with you guys..it looks like one of the areas of the huge suspension bridge at either GV or HSR. But just in case you guys are wrong, I'll say SS Route 5.
You gotta drop a hint. Seriously. I gave you one yesterday...actually I gave two! This one's way too dark and too cropped. Can't even tell what the pic is, honestly.
