I think the oil boom screwed it up, up to a few years ago it wasn't too hard to get permission.I have hunted the area south and east and NE of there since 94 with a few years off here and there. Did not go last year. There is a big refuge south though most of the big ruges and duck concentrations are SE of there. Your big concern is going to be the new tresspass law that is just coming out of committee as of last Friday. Still some details, but ND will go to permission must be obtained before hunting. Used to be un posted and you could hunt. Just like MT was until 95 or so. This will change things in a huge way. Most of the good Mallard hunting is field hunting with scouting in the evening and hunting the next morning. The roost water that is accessible is shot off pretty quick. Landowner permission can be tough, one of the guys I hunt with has over 10000 acres and both the other guys we hunt on have 15+. Tough to find them if you don't have their number! IDK the good days might be over for freelancing.
