Here is a picture of Isaiah starting out on his climb.
Here he is about half way up. His little arms and legs were getting tired, but he kept going.
If you look closely, you can just make out Isaiah climbing on the outside of the tower about 50 feet below the crows nest, where he could finally get a rest.
Note: Of course this is only a joke. Just wanted to see if anyone is reading this blog. I would never let Isaiah climb up this tower. He really did want to climb it, but I only let him go up about 10 feet for the picture. Nathaniel, Jonathan, and I really did climb it, but we used harnesses and a safety rope.
