OK, I'm riding and following another rider, we come to an intersection, light is steady green, we start through intersection when rider in front hits his brakes hard, I also hit my brake, rear only, and just before coming to a stop, I tip over to the left and hit my head and my front tire makes contact with his rear fender. I get up, pick up my bike,no damage, helmet has slight scratch with no cracks or holes, restart and continue on to the VFW post where ride ends. I am fine with no problems, but I wind up, 30 days later, in the hospital, brain bleed, surgery, 9 days ICU and then to rehab for 3 weeks. I am back to normal now, I want to ride but wife wants bike to go. Can anyone give me a tip as to what went wrong? There were no other riders aroung at the time, just the bike in front of me and he stated that he heard me skidding and knew there was going to be contact. I guess I must have frozen because I did not take evasive action.
