There where a lot of trees down from ice in the Atlanta area. Luckily, I got one of my neighbor's trees down before it freezed outside. It was rotted in the middle about 30 feet up and surely would have split just from the ice expansion. It split taking it down, but, luckily for me I had wrapped it in chains and had rigged three cables around it as a precaution.
Ice storms are good for the firewood business :-)
