Run an add in the local newspaper in the area you want to lease. List the sportsman groups you belong to and a contact number (call collect). I will bet you have more land than you want to hunt.
Land owners want to make money on their land....
You want insuranse..... get a few guys together who are NRA members ad form a "hunting club". NRA offers CHEAP insurance....
Get "Creative" folks, Base Camp Leasing has done it and leads in locking up property.......
Duplicate the "model" and prosper.......
