A friend of mine last year (he is still a friend now) climbed a tree to cut off a few branches for a neighbour, he has done all the courses, he owns all the right kit and yet he still managed to cut through the branch he was standing on (something out of a cartoon maybe)with a chain saw! A few weeks in the JR followed by several weeks at work with his feet elevated he still can't explain how it happened!
Not the zenith yet then.
& then there was the idea to surge!
