The best days to go are Friday and Saturday from what I have experienced. I haven't been there on a SUnday, but could imagine some folks would be packing it up and heading home by that afternoon. The tough trucks, rock crawling, and monter trucks should still be there doing there thing though, just the show trucks and maybe a few vedors would eb packing it up !! I am debating the same thing !! Go Friday by myself and make my son mad cuz he had school and had to miss it or go Saturday and then I have to miss school(college), but I could take Zac with me or go Sunday when neither would miss anything at home, but not sure how the show would be on the last day !! I have a 2 1/2 to 3 hour drive.
