Not sure, but it is usually around this time..here is some info..maybe you can call them tomorrow and find out for sure Address: 602 N. Dean St. Adrian MI USA 49221 Telephone: 1 517 563-3007
It's a decent size meet for Michigan although turn out can be weather dependent. My dad, brother and I hit it every year, although I'll alittle too far away to hit it this year.
