OK, here's what I got- Osceola-july 3rd, july 10th, august 27th. Guthrie Center- july 9th, august 20th, september 4th and 5th. Greenfield-july 24th, august 27th, and sept. 17th. Theres also two at Anita, one on july2nd but I dont know the second date yet. Mt. Ayr is having one on july 17th and another in late summer or early fall TBA. All of these are obstacle type mud races with the exception of Mt Ayr which is what you might call Chicago style (like monster trucks sometimes do)- theres only one oval shaped track and the competitors start at 180 degrees opposite one another, but moving in the same direction, whoever gets bak to where they started from first is the winner.
