Hi guys, MN guy here... a buddy recommended ND for geese and duck.  Any general areas I should look at?  Devils lake?  Public land or guides (Open to either)?

Any feedback is appreciated

Not a resident but have hunted ND multiple times over the last 20 years.
Land access is hit or miss.  ND's tresspass laws allow for unposted land to be accessed without permission, but more and more land gets posted every year.  that doesn't mean you cant hunt it, but don't be surprised to hear no when knocking on doors.  

Devils Lake area is hard to get onto private land, and public land can get crowded.  Lots of leased land from guide services in that area.

Southeastern part of the state can be good hunting, but you'll have pressure from Fargo residents and western MN non residents.  

North central through south central areas see good migration numbers, and good local duck and goose numbers when conditions are favorable.  

I'm afraid what you'll find this fall is that pretty much anywhere east of the oil patch and the badlands will see a significant increase in hunting pressure due the Canadian border being closed and over the counter licenses for ND.

Best bet, if you're going by yourself, get on the ND game & fish website, get the PLOTS map, study google earth, throw a dart at the map somewhere south of a line from devils to minot, try to book some lodging, and go.  You'll kill ducks if you aren't picky.  a dozen floater mallards, a half dozen goose floaters, and a 3-10 dozen decoy field spread if you have it will get you some shooting.  
Don't bust the roost.  Hunt smaller water in between the roost and the feeds if you aren't a field hunter.
Divers aren't targeted too much besides on Devil's Lake, if you're a diver hunter you'll have shooting.

Best bet, talk to your friends & co-workers, odds are somebody you know makes the trip annually and has for years, and might be willing to add you to their group.  Going with some experienced guys really helps you learn how to scout (the single most important part of hunting the dakotas), how to hunt transition sloughs, how to have a plan A, B, & C each day in case you get beat to a spot, and groups that return year after year often have their lodging booked well in advance which may really come in handy this fall.

Tornado- thanks for all the good info.  Good luck this fall.
