Well since you are already in WI you are near argueably the best natural resources college in the country, UW-Stevens Point. They have a strongly developing criminal justic program that goes with the natural resource majors. I don't know all the details so I'm not sure on the language of it. I am currently in my 4th year at UW-SP in wildlife managment. Give Dr. Holsman a call or email and I'm sure he would be able to help you out with any questions you may have. He runs the criminal justice portion of it mainly and is the leader of SLEA (Student Law Enforcement Association) on camps. Maybe you'll find there is a different major you'd like better in the natural resources relm. I've thought about the warden part but I love hunting to much so didn't do it. I have a few buddies who have gone through the program. Its 1 semester at the tech college next to point to go through the academy and the rest of the GDRs and natural resources parts are done at UW-SP. Good part is that once you complete it you can be a warden, ranger, police officer, ect... so you have options beside the warden part. Here is his link and Point is a very good school.

. Good luck and let me know if ya have any questions. WCL
