I was keeping a sharp eye out for any funnel clouds, seeing as how Springfield, not that far away, got actual tornadoes last week. But none showed up.

We did have an actual power outage, caused by a downed tree. Which resulted in an actual conversation between two human beings.
Mainly, we talked about the books on our Kindles, and what we were reading lately.
REAL SOON: will post about the Boston Folk Fest.
