A place to look for county landowner map is Central Publishing in Iola, KS. They have a rural directory that shows the roads and road names, ownership parcels down to 20 or 40 acres and where the landowner lives​. Another thing you could do is make up a liability release contract stating you won't sue in case of an accident. In this sue happy world it could help put the odds in your favor. A better option would be to have liability insurance but don't know if I'd go that far just starting out. Also with the extremely high costs of operation and very low profit margins a lot of stuff is getting leased out to help subsidize income. So be sure to mention you would be willing to avoid hunting around deer season.
