I go every year and plan on attending again this year. It's a combination of pumps, signs, and assorted. Every year it's different. One year pumps will be strong and signs weak and sometimes it's the other way around.
It's not the largest show, but it's indoors with a modest amount of vendors.
It kicks off the petro season, Dayton Gas, Michigan Gas, and Columbus Gas are easy drives from NW Ohio.
