I've been twice and i've still never made it the whole way round & each time I was there for 3 days lol
I always leave the truck building till last as they don't interest me as much,
study the map and floor plan and try to prioritize before you get there
it is overwhelming and easy to get side tracked by ladies with posters

also lost some time watching those crazy rock climbers and the drifting
good luck

p.s I can't go this year so every has to post pics asap
