Outfitters provide a service to clients, mainly out of state people. Around here if I shoot a very good deer it is going to be 125" or so. For me to get a good chance at a 160" + deer it will be necessary to go to another state. The outfitter will provide the land to hunt, license application, tags, a place to stay, place to eat, transportation as well as a guide that is very familiar with the area you are hunting. I've never used an outfitter, but wouldn't mind paying for a good one. Besides that, some states/provinces require an out of state hunter to hunt with a licensed guide.
