A father of 2, a husband of 1 & been playing on people's roofs for over 25, yrs till I thought I'd try flying off one. Now I estimate & bid & keep the other guys playing fiddles on the roof & singing "Up on the Roof" (we really did sing up there). I wish singing was a less dangerous hobby, I'd have taken it up as a trade long time ago & thrown away the saftey belts. Barry
