Hey Mark,
I am going down Saturday all day as a few of the locals from our weekly meet got cars in there. There is a lot of variety to check out, and fully charge your camera, I usually have to recharge my phone a few times.
Yeah the results of the surgery varies, but a few benefits for me was being able to cut the grass without being laid up for a day and a half, not to mention the small trees I would take out sneezing lol, as well as not having a sinus infection every year. Mine they had to break up pretty good, 1 side of my nose was smaller than a coffee straw, the other was a normal straw, so hence the black eyes.
If you're there Saturday give me a call, either way enjoy the show, also check out the rat rod section, its amazing the crude engineering that goes into some of these rides.
Regards,
