So, it turns out the second power failure and the loud noise was a birch tree falling at the end of my driveway. We never knew... until my neighbor, who we share the driveway with called and told me. DH had gone out and he saw the tree was all down and cut up, but not the hole in the ground. I guess Concord Power and Light came and did their thing quite quickly.
There's a lot of trees down in Sudbury and Wayland, not as much around here. Western MA is a mess, as is Vermont, as Jolt said. They had to close Rt. 91 on the MA/Vt. border, because of flooding. I just got an email from my friend in AZ, who is originally from Montreal. Her relatives said the storm is wreaking havoc up there now.
Not looking forward to driving to my client's homes tomorrow, but I suppose there aren't too many trees in the city!
