I've done 4 of them. Opening day, a little league game, an OSU-Michigan game, and the Little Brown Jug.
Good to see the Little Brown Jug on the list. I believe it's a hidden gem in the state of Ohio that very few people even know about. It's a full day of great racing, gambling, and lots of beer drinking, all situated around a county fair racetrack and amongst 50,000+ fans.
