American Parkour

Hey im in a group with me and some friends and we started parkour a few years ago and now we wanna get serious. We have found spots to do basic stuff but we wanna move further. We have the option of uptown but we dont want to get into trouble with law or anything. I really need to know if where a lot of great parkour spots are in Charlotte, North Carolina that will allows us to do it without getting into trouble.
