I've seen a couple happen in front of me:
1. We were heading to Prescott, via 89 out of Wickenberg. About half way there, a few doves flew in front of the rider in front of me. He missed the first, but hit the second in the face. Luckily, he was wearing a full face helmet. His head jolted a bit and was able to maintain control of the bike. He stopped soon after and when he turned around, his face shield broke, leaving a big hole in his face shield. He somehow managed to keep from wrecking, but what a sight it was to watch. BTW, a dove was hurt in this incident(actually died).
2. A group of us went for a night run around Lake Arrowhead(Wichita Falls, TX). While following a Kawi on a left turn, a truck came around the turn(opposite direction) and I think it spooked him. He ended up going into the grass and crashed. Nothing serious, but it did scrape the bike and the rider up a bit.
3. (Worst story)Their is a group of riders and who ever else shows up on
Saturday nights to meet up and hang out. Usually sometime during the night, we usually go for a quick run around town. On this night, three of us decided to go on a quick run. The first two pulled out of the parking lot and turned right. Just as we started to accelerate(I was third), a young girl with a newborn driving a car(she was driving the opposite direction) made a left turn in front of us. The first rider hit her front right corner of her car. It was a really bad impact. This is mainly because when he hit, not only did he gain air time, his bike's rear end twisted to the right. So it spun him as well as tossing him. He ended up with some bad internal injuries and lost half a leg(above the knee). He survived it and seemed to be in good spirit when I last saw him.
