Philly, my condolences!
Now that we've lost our sunlight after DST ended it's my most hated time of the year simply because there is not one spot on my 55 mile drive home where there isn't a stinkin' deer crossing. They infest this area, like roaches in a So. Florida kitchen (no offense meant to our So. Florida members !).
I've been around Bucks Cty. several times & it's pretty & wooded & positively says "deer".
And, I'd be willing to bet, there isn't much hunting taking place around lo. Bucks!
Take my advice though, my friend, if ever in the future you find yourself in a similar situation do not weave. Odds are that you'll end up inside a tree while Bambi scampers off. I've seen deer do some pretty amazing things (besides standing in the middle of the road waiting to get goosed by a Crossfire) including things like leaping out of the way at the very last second before impact.
