I will present a demonstration but no instruction because they are worried about people actaully climbing- except me of course. There will be a number of tree planters there (I hope). I'll do my best to convert as many as I can to the real thing-climbing trees, but at a later date at the TCI school.

I know Tim Womack. He is a great story teller, arborist, and ususally rides his bicycle in the Tour Des Trees to raise funds for the Tree Fund (ISA).
