It is hard to imagine running a hunting preserve without one. I guess if people just pay to come and hunt by the day or something it would work.
When our groups come back to the lodge it is where we get to really know them, talk about the deer they saw, talk about the hunt and just get to know each other. If you don't have a lodge you are just leasing them the land more or less to hunt on for a few days. It is an entirely different experience - which some folks might go for if it was cheap enough.
