Not until the next day did Margy find the source. The top 30 feet of the big pine right next to the garage/shop had snapped off. It didn't hit the shop roof, or the porch roof, or the lamp post. It didn't take out the power line or the young pine I've been encouraging. It took down one branch from another tree and kicked a bunch of dirt on the steps. It couldn't have fallen any other place and done less damage.
Now I have to see if I can drop the remaining thirty feet in the same place. But first I'm going to do something really sweet for someone to replenish my good karma.
Today I was thinkin' I might leave 10' of this tree standing and make a totem pole. That'd be cool wouldnit?
