The Mid-America Trucking Show opens to the public Thursday at 1 p.m. and 70,000 of the industry’s closest friends are expected to drop by. Aside from 1.2 million square feet of exhibits, a free concert with The Marshall Tucker band, endless freebies and impressive giveaways, MATS features a massive display of custom trucks. The PKY beauty truck Championship winners are announced Saturday. Here’s a quick refresher from the show a year ago.
