Robby,
Yes they do have a website. They started in Rock Springs, Wyoming with a group that split from MDF. That particular chapter was the top grossing chapter in the nation for MDF. They got tired of sending their money to MDF with little in return. The representative I spoke to spoke highly of MDF. The rep explained they just have different opinions on how an Organization should be ran.
It's my understanding with Muley Fanatics 70% stays with the local chapter, and 30% goes to the main office. That differs from MDF as 80% went to MDF, and 20% stayed with the chapter. MDF is putting more money on the ground where it was raised. I think it is a great concept, and I hope MF will be the next great habitat organization.
