Skiper, the poop on the side of the saddle was absolutely from the deer. The poop in my shorts was another matter entirely. The deer nailed me in the front fender, broke the mid fairing on the Connie, wrapped around my leg, broke the right "antler" (a cast bracket that the pannier attaches to), busted the pannier off the broken bracket, and my headlight went out.
I had seen the deer standing off the road and slowed down to about 45-50 and was almost past her when she decided she had to be on the other side of the road and attacked me. It was very nearly dark and when she hit me and the headlight went out, I couldn't see the road. But I had seen a parking area on my left and headed for that. When I stopped, the parking area sloped too much to the left for me to be able to put my kickstand down. I was just sitting there when my riding buddy ran up and told me to stay put. He had picked up the pannier and put it down beside me while he ran back to pull the deer out of the road.
By the time he got to me a pickup had stopped and the driver had thrown the deer into his truck and taken off. Steve got my pannier back on the bike and told me to follow him. I did and he ran at about 35 back to our lodging about 10 miles away. We looked at the bike and saw the cracked plastic and went to bed. It wasn't till the next morning that we noticed all the deer poop on the saddle. I'm here to tell you that deer poop attaches itself to the very molecular structure of Russell saddles if you let it dry overnight. It took over an hour and two or three buckets of warm, soapy water to get the saddle cleaned up.
We drove 60 miles to a NAPA store that had the headlight bulb I needed only to find out that the one on the bike was fine -- it had just come unplugged.
