Thanks for all the well wishes.

If anyone has any thoughts or similar experiences I'd really like to understand how that stick got in my spokes.

I guess I will never really know, my current guesses are wind blew it in there, I ran it over and it flipped in the spokes somehow, a car drove by and somehow propelled it in to my spokes, some nasty kids were hiding between cars and stuck a stick in my spokes...

The car causing the stick to fly in to my spokes seems plausible because the other cyclists mentioned a car, but he could also have thought I was closer to the busy intersection, that I had just passed, and a car had hit me there. I have no recollection of a car coming from behind and then passing me or coming from the front. I do have a very good memory of the other cyclist's light bliking as he approached from the other end of the block and then WHAM!!

At least I am convincing myself that the odds of this happening again are very slim. I might have to go buy a lottery ticket.

Well I am off to Hawaii tomorrow. The trip was already planned so I guess it will be a recovery trip for my shoulder.
