I climbed the tree, despite the clearly marked “no climbing” sign affixed to the ground in front of it with a green plastic stake. I climbed it because of the sign, really. I dug my sneakers into the rough bark and pulled myself up into the Y of the trunk, rose, wobbling to my feet, and grabbed the net heaviest branch within my reach. And up I climbed, until I had nothing but leafy twigs to grab hold of. Then, hoping to glide on faith, I held out my arms and jumped as the wind caught me.
