I was pacing a group of road skaters around the lake at Eldorado park in Long Beach. I was riding my track bike with one front brake. As I lead them into a sprint on the last straight away I was at 28 mph when some dodo started feeding the geese on the other side of the road. What seemed like 100 geese moved in mass across the road in front of me. I tried to slow but the skater on my wheel put his hand in the middle of my back trying to slow himself as we hit the flock. I don't remember going over but I woke up with a cracked helmet and a right arm that was paralyzed for 7 months. I had temporary amnesia. My rear wheel was potato chipped. Did not know where I was or how I had gotten there. It was like I had gone to bed in my own bed and someone transported me to Eldorado Park and woke me up in the middle of the road. I guess I may be the only cyclist that has been taken down by a flock of geese.
