I've had a mule deer come out of the woods in front of me when I was on my bike. It was like it materialized. Fortunately I was going slow enough to miss, and it helped by the way it got out of the way. But it could have gone much worse, and there was little I could do about it.
After being declared the winner of that bout, I celebrated with a bike wash & 2 shots of JD. :-)
