I went out with a group leaving Modesto Saturday. We were in a loose pace line headed North on McHenry. The guy in front of me took his right hand off the bar to point to an object on the ground. Something went wrong has he reached back to his bar. His front wheel turned and he ended over the bars. There was no room to go around him and his ankle was right in my path. I went over it and stayed in control. I thought I was going down for sure. We were doing about 15MPH. I must of bunny hopped the front wheel a bit as I don't remebr much of a bump. He ended up with lots of raspberries but he still finished the 40 mile ride.
