Looking at the picture a little closer, I can say without a doubt that it was not taken this year.
I hung out at the AAR, T/A reunion tent a lot of the weekend and I notice that it is not in the photo.
Having spent the weekend in this part of the showfield this year, that pic is definitely not from this year. It wasn't close to that packed. I also don't see any Superbirds/Daytonas in this picture that would be right in the middle of it if it had been taken this year.
