After the April 28, 2011 Super Storm that rolled through north AL, my BIL lost two giant Red Oaks in his front yard. They could have done massive damage to his house, but both missed it, than God.
In any event, I went over to help with cleanup and when I got there, there were like 30-40 people chain sawing, hauling, cutting up and generally just cleaning up the place. I asked my BIL who all these people were and he said: "I have no clue whatsoever, they just all showed up!".
It was pretty cool. I got a ton of Red Oak firewood out of it as well.
