One of the reasons that the constant gridlock in Los Angeles is legendary is because there's no real subway system to speak of. So while it's there, I don't think it'd provide much excitement.<br/><br/>An amusement park - Disneyland, after hours, or something like it? - could be fun, but I think we'd need to contain the scene to one specific location in the park. I don't think a camera crew would want to set up, shoot a little, stop, move, start shooting again, etc., etc., etc.<br/><br/>I like the other ideas, too ... they just don't have that "we're<em>really</em>not supposed to be here" vibe that a stadium or amusement park has, IMO.<br/><br/>If anyone has strong feelings about the location, please let me know - otherwise, it'll be "gangbang in a big mansion". Which is fine, 'cause that's still hot. :)
