I still can't believe how bad that bike took a hit and you walked away. (Ok maybe limped...glad you are all healed up and riding again.)
I remember when I realized that things were about to get bad. The next thing I remember is tumbling and then jumping to my feet as soon as I stopped moving. My first thought was to move out of the road so I didn't get run over. I don't remember the actual impact or coming off the bike, only the before and after. From looking at my helmet, it appears that my head hit the guardrail and the road pretty hard.
