Earlier this year I was with some friends in the vast wasteland of the Arizona strip north of the Grand Canyon. In the span of one day I had a coyote run along the side of the road with me, a big buck jump out in front of me (then I watched it plow through a barbed wire fence to get out of the way while I skidded to a stop) and I ran into a cow. I lucked out, with only a broken mirror and scratched helmet to account for the sliding and rolling over that the bike and I did.
In the end, cows are evil. Just saying. Hope you mend well. Did I mention that cows are evil?
