Last year it was in the beginning of March if I remember. Like the first or second. Sharpen up your coyote skills if you plan on entering it costs either fifty a team or fifty each I cant remember, the winners killed 17 yotes last year, second place came in with 15. I think they gave out like $250 for the biggest male/female though. I wish I would of taken a pic of the pile of dogs that were in the airplane hanger, it was huge. I dont think I'll enter this year. There were over seventy teams that had entered. They have a descent gig to keep guys from cheating, but its not failsafe.
