Hi, Bill. I have been there several times in past 3 years. They actually have 3 large meets there each year. May, September, and in November. The November one is just on Friday/Saturday November 9th and 10th. ( the others are Friday to Sunday events ) Look up
www.ohioswapmeet.com. They have cars for sale, car show and swap meet. I have never been to Iola, so don't have anything to compare it to, but it has a few hundred vendors. I hope this helps you . Personally, I love it, and I just live 1 hour away.
