Growing up in NH, I am no stranger to road kill. Squirrels, raccoons, deer, and the occasional cat or dog (sad). The only victim of mine was a snake I ran over on a country road headed to hike my favorite mountain.
As a city dweller, I've seen possum (Saint Louis), and a lot of squirrels, and, ugh, rats.
Usually I see the victims once they've been well-mashed or after some rain or something.
But there was a week in January that I saw fresh road kill every other day. I mean like blood you could soak up like gravy.
Not only was it kinda gross, but it felt like a bad omen. I believe in stuff like that.
Knock on wood, nothing's really bad yet happened.
