Long drive from Maine to Vermont this afternoon. On I93 just outside Manchester, nearing dusk, a flying flock of birds caught my eye. Crows. A lot of them. As I sped past I looked over as best I could and realized the trees were full of them too: a large group roost right next to the highway.

Hour three of driving.
What's that? Roosting flock of crows.
Wow! Hundreds of them!

And then a bit later:

Dark, empty highway.
After five hours, almost there.
Oops! Going 90.
