Back again! Now I am trying to get siding onto a 12-foot high treehouse surrounded by trees. As you can imagine, it is a little challenging. My wife and I busted our butts to get one piece of 4x8 T 1-11 up to the deck. Not easy. yesterday my neighbor and I used a pulley to get a 4x6 sheet up there (thanks, Jonathan!). Not much easier. I bought a block and tackle, let's try that!
