was here for the SEMA 2009 show.. it's a massive space.. lots of walking indeed.. but the maps are all wonky. the help desks aren't very helpful, and quite frankly, it's not a nice looking building. .... BUT that being said, it does what it needs to do, and that's to be a convention center.
at least we didn't drive here, cuz i have no tips for parking/etc. :)
