I ride at night, mostly, and I had 2 deer cross my path far enough ahead, that it wasn't a big deal.
I was watching them on my right and thankful that I didn't smack them, and then, ALL OF THE SUDDEN, their buddy runs right in front of me, from the left, to join them.
Well, I hope that was exciting enough!
There are a lot of conservation/green areas in my neighborhood, so I really have to watch-out at night for raccoons, deer, possum, turtles, etc.
