Nice report greenluck. There aren't any "no climbing" ordinences on the books in my town. But in the past I was given the verbal no go by the Streets & Parks general forman. However, last year while we were in the process of trying to procure a tree to use for our climbing academy, he has started to change his tune. Infact he was the one who suggested the parks that we may now use. His change of mind has come about largely in part to hearing repeatedly, exactly what tree climbing is, how we take care of the trees, the safety of our equipment, ... I think a lot of the resistance is simply a matter of the old "why would you want to do that." or "We never did that before." mindset. Like you, I too offered to put the powers that be on rope. Some of them still think I'm a little goofy. But they're comming around. It's all just amatter of good PR and time.
Again, nice report.
