Last Saturday I was sitting in my stand and a tree about 10 yards away suddenly went "pop". A limb about 30 or so feet up just snapped and came crashing down. I nearly pooped myself as I was looking in the opposite direction. Had 3 or 4 squirrels running around a few yards from me and they just went off barking. 30 seconds later the woods went silent and they returned to gathering acorns.
