What a great thing you are doing! There is a certain attraction to trees every kid knows. But to take a physically challenged kid up to experience what most able bodied children already know is the work of a great person. It is one thing to have the skill of tree climbing but to share your skill with one not as physically fortunate as you puts you and your group far ahead of most tree climbers. Please keep sharing what you are doing so others can benefit from your experience.
