The storm had already passed, so I was surprised to hear a loud ‘crack’ and then an imposing ‘thump’ outside.Walking to my front yard, I noticed an enormous dead branch had fallen off a white oak tree and crashed onto the ground.This massive tree has been growing quietly in my yard for many years. With a 4-foot diameter trunk and crown spanning more than 100 feet, it looks both ancient and majestic. But I rarely pay it much attention.
