I am actually not aware of THAT one?
The one I was at was in Johnstown. It's been going on for YEARS but I've only been going for a bit. Back in the day, my Labor Day event was the National Coon Dog Field Trials in Kenton, Ohio. It was b-i-g but it grew too crazy. The drunk campers were one thing, but when they expanded in to evening entertainment (concerts) it simply grew in to a monster and the owners just pulled the plug on it.
As I've heard it, a bunch of the regular vendors went to Lima to the Allen County Fairgrounds for a similar event, and another large bunch went to Johnstown.
Next year, I'll finally get it right. Johnstown on Saturday and Lima on Sunday! (range day on Monday!)
