Lightning struck a big oak on my home course sometime in March before the course opened. There was a neat facebook picture but I can't find it now. When I played my first round of the year a couple weeks later there were shards of wood from several inches to a foot or two long all around where the tree stood for 60-70 yards in every direction.
Apparently the lightning hit it directly and made a good enough connection that the heat caused all the water inside the tree to be instantly converted into steam and the tree essentially exploded. I've heard of that happening but had never seen it and didn't realize it happened with enough force to spread such large (and probably deadly) pieces of wood shrapnel over such a wide area. Nevermind not taking shelter under the tree getting hit, even a tree way over on the other side of the teebox wouldn't have been safe!
