No problem's at all. SEMA was awesome, tons to see.. In fact... too much to see, I didn't have enough time to see it all and I was in such a dazed state trying to see everything I really didn't get to shop.... By the time it was time to head home, I had less than a hundred bucks of purchased goods and none of it was car related aside from the SEMA shirts :P
I'll probably post a link up to some SEMA pictures once I get around to sticken them up on flickr or something. I think I took a few hundred or so.
Definately wouldn't have hurt to have a planned route for checking out sections instead of wandering around. It was big ! Should have put the maps to more use.
