How much do you think the tree weighed? I ask because Steve Justa, in his book Rock, Iron, Steel, made mention of the fact that he once walked 2 miles with a 200 lb. vest (he made the vest himself). I'm guessing the tree didn't weigh nearly 200, at least I hope not, but hauling something for 3 damn miles is still pretty good.
Maybe this should be the T-Nation Christmas challenge - walk 3 miles carrying something (doesn't need to be an actual tree) that weighs the same as the tree!
