Its probably a long shot and will require a little research. The link will list private property (plat descriptions) that is open to public hunting. You will need to get a hold of a plat map to locate the property. Then you would need to check it out. Make sure it is still enrolled in the program. Both the MFL and FCL programs are pretty similar. There doesn’t appear to be a ton of acres open in Buffalo county, but you could also check out some of the surrounding counties.
