Climbing Windows, Walls and Mountains

William and Samuel got their rock climbing experience this past week when their dad Bill, took them rock climbing and to "Rise Up Downtown":)

The other day when I was babysitting Samuel and William while Ruthy and Sarah were in a 5K race, I looked behind me and saw Samuel climbing up the back of the window behind me....I remembered then that he had just experienced rock climbing and wall climbing which led him "naturally" to somewhere in the house that would be fun to climb:) Is it "spider boy"?
