Dangerous with a Saw

Working on Dr. Peter Houck's cabin near Washington Pass. Here, I am "adjusting" one of the TJI rafters for a 12 foot cathedral ceiling with a circular saw. The kid to the left is hanging onto one of the clamps that holds down the saw jig. He is keeping the joist from falling over. Cuz, nothing is nailed in place yet! And, yes I am standing on the top step of a 6 foot step ladder.
