I ran over a big snake on my bike the other day. I was going fairly fast... I reacted fast enough to lift the front wheel over it, but I have to think my 210 lbs on a 23mm rear tire was a bit.... bad for Mr. Snakey.
Almost hit a turkey this spring. I was going ~ 25 mph. It would have been ugly. It also would have been ironic if a turkey killed me, considering how many of them I've kilt.
Hit a cat on my motorcycle way back when. Luckily I was going in a straight line.
