I did it for a number of years.Simply call the dispatcher at each police station and highway patrol and ask to be put on it. My sister was a dispatcher and that's how I become aware. Now be warned the first time they call and you don't go your off the list! I got calls at any time you can imagine. I had a job that wold let me leave if you don't you wont last long. And some times the highway patrol calls can be a ways off. Most calls of coarse is night time. And it will get to be a pain in the A$$ after a while. I would typically get 15-30 season. They will write you a permit and it don't count against your limit.I always heard bad things of road kill. But with all the deer over the years, I only threw one away because it was internally bad. Every thing got ruptured. For most its usually a broken neck or broken leg and most are usually front. So i didnt worry as the biggest part of the meat is the two hind quarters any way. It worked for me and raising 5 on mostly wild game. Wish I could still do it.
