Yikes, Ive got a big cotton wood tree and few years ago I was out working on a car in driveway when I heard a crack, looked around and saw about a ton of tree come crashing down in the back yard right ontop of another car of mine... somehow my car was completely buried and totally unharmed.. freaked me the hell out.
it was that same limb that nearly killed me when trying to clean it up, it was still sorta stuck in the tree, when it hit the ground, it bounced and sent me flying like a ragdoll about 30ft across the yard... be weary and carefull of cleaning that mess up! there could be a few limbs in there with alot of potential energy stored from the way there all bent out of shape.
