The numbers game that is SEMA is nothing short of mind-boggling. Two million square feet of automotive excess divided up into 11 sections. More than 2,000 new products including parts, tools and accessories are beholden upon a good 100,000 or so SEMA-goers. More than 100 countries' worth of industry leaders, movers, shakers, even those not so inclined to lead, move or shake, roam the city of sin's convention center depths in search of what they-and those pushing it-consider the next big thing, which indelibly ranges from anything from silly donk accessories to the not so silly go-fast bits we usually seem to rave over. Much goes on at the industry-only, once-a-year Vegas-based gala-like event, but as usual, what we care most about are the parts.
