On an afternoon ride yesterday on a secondary road I spotted a deer off to my left. We were just entering a sweeping curve to the right at 55 mph. I live in an area with a high deer population and am aware their movement is often unpredictable. The road had a broad steep ditch and was bordered by woods on both sides. The deer started running diagonally through the ditch in the direction I was traveling. I immediately started to slow my speed to give the deer plenty of room to cross in front of me. I was using my engineering background to do quick mental calculations of the angle of approach and the point of intersection (lol). As the deer approached the center-line of the road, she must have decided it was too much bother to go around me, so instead she decided to go over me. As she left the ground she stretched her two front legs forward and tucked her right rear leg up to her chest. The rear left leg extended down and back. As she went by, I heard her left rear foot strike something but it didn't affect the stability of the bike. I did get a really close up view of the deer. A quick stop to inspect the bike showed just a little scuff on the fender. Guess I will have to do a little polishing today. Ride safe out there and look out for critters.
