The big RV show in Kansas City was last weekend at Bartle Hall. Bartle Hall charges all those dealers to use the facility based on how much of the hall they use then that cost is passed on to the attendees. This year's ticket prices was $12 per person for ages 12 and up plus parking.
I did not attend the show this year as we just bought a new TT in November. The last time we attend a show, I did get a bit irritated with all the Good Sam literature and advertising bombardment (the major sponsor of the show) and booths set up that didn't have anything to do with RVing. If I needed home window and gutters info, I'd attend the home improvement show later in the spring.
