MUCH cooler this year and somewhat smaller, too. I was there early in the morning for the show, which may explain why there were fewer cars than last year. Last year was in the 90's and this year, in the 70's. For me, that's nirvana.
I was able to use my 40D with both the 12-24/4 Tokina and my new 10-17/3.5-4.5 Tokina fisheye. I've only got a few in here using the 10-17, but it's one nice lens. I look forward to doing a bit more with it over the fall.
