Hello Centalic & welcome to the Freedom forums, this is the second parkour channel I've said hi to. I will say the same thing I said to the other one by saying that its not a great idea to trespass while doing this, as you are giving evidence online that can actually be used against you if you get caught. I'd suggest you start off doing simpler runs on public places where its safe legal. Then work to get permission to do these. Obviously many will say no but its better than being arrested every other day. Just keep that in mind.
