Hey that tip is great if your just playing a backyard style game like you were. Tree climbing is against most field rules due to insurance reasons. And usually being up in a tree is the last place Id want to be against more than one person. If I saw you in a tree, I know that you would have only one way down. And a good fundamental rule is to have more than one way out of a sticky situation. Please dont take this as cruel critisism, just trying to help you out.
