George, all the details can be found at
www.semashow.com. It truly is a great event, but bring your walking shoes! Figure on a full three days to see everything in the SEMA show convention hall. The AAPEX show in the other hall wasn't that interesting to me when I attended last year, as it's mostly oddball tools and non-performance items.
Wayne (LTHL VPR) and I will be attending this year from Wednesday to Saturday.
P.S.--Taking a power nap before dinner is the key to seeing all the booths at the show but still having enough gumption to stay out all night!
