Well.... the show lasts until Sunday and IIRC the awards are at 3:00pm, and you must be present to receive your award; so... there's a chance there will still be a crowd around. I know that we will still be there on Sunday, but the main day for the event will be on Saturday.
We would love to check out your truck, but I'd hate to see you waste a 3.5 hr trip up there for only a few hours to then turn around and head back home. Just tell your boss you need to take a "clunker" out for a spin... dash home... and head to KC!
