I was in the second from left lane, and pulled into the left lane (the HOV lane) to pass a car that I'd been stuck behind since the toll booths at Route 28...
...and promptly ran over a dead possum in the middle of the lane.
(At least, I think it was dead. It might have been playing... well, you know. It wasn't playing any more, that's for sure.)
I didn't have a chance to avoid it, so I could only reflect on the money I'd just dropped last month on new front struts, tires, and alignment as I waited for the THUD.
