Taking Down a Tree

So I watched while my son took down a tree in our back yard yesterday.     He climbs like a monkey - (a compliment for this application)...he has climbed trees from the time he was very small.  I would look in the backyard in our country home in upstate New York, and see how high he was in the tree and try hard not to freak. I would tell him to come down to some lower branches.  Fearless...his whole life.  Thankful for safety yet again as he presses the limits.
