Concur on that. A friend of a friend died during the Galveston rally, after hitting a trolley track at <10 mph (I think). Banged his head on the concrete.
Mark: I didn't know you got a concussion out of that. Are you OK now?

"OK" is a term that many would disagree with regarding me.

I am somewhat back to my normal self.

I didn't think it was that bad - just ringing in the ears, a little trouble seeing clearly for a minute or so but it was over quickly. Dr. Lyn-Del did a quick check at the BBQ later and said my eyes were clear. But I went to my usual doctor when I got back because I wanted to get an x-ray on the shoulder and she told me it was a concussion and to take it easy. That I should stay off the bike for a few weeks. This after I rode back from Houston to Arlington. So I weighed her advice and then took a round trip to Austin and College Station/Snook.
Thanks for checking.
