I have this little problem with almost taking out critters (or almost being taken out by them) while biking and skiing. Last weekend I almost hit a red squirrel at the NE Gathering at the Loaf. There were several witnesses. One said it was a chipmunk, but it wasn't. (I was very, very close to it.) This has happened to me a few times while skiing, including at least once with an ermine (weasel with winter coat). And it's happened LOTS of times while mountain biking, including near-collisions with skunks (twice), porcupines (twice), and wild turkeys (at least three times), raccoons (once). as well as innumerable incidents with chipmunks, squirrels, and mice.
I about ran right into a donkey biking on Tuesday. Thing couldn't make up it's mind where it wanted to go.
