I helped out on a Family Tree Climbing day. The idea was to provide canopy access to those who would not normally be capable. From small children, to the over weight and a few wheelchair bound folk. Being in the top of the tree when one of the disabled lads came up with the biggest smile I have ever seen, was a great experience. He doesn't get much opportunity to get out of his chair, let alone be suspended above it in a tree.
Great to see so many of us providing such great experiences to others.
