Dave, I was just in NoDak for the first week of October.
Pretty close to Devil's Lake (just South).
Pick up a Conservation "PLOTS" guide (Private Land Open To Sportsman).
It's put out by the ND G&F Dept.
This stuff is all open...free access:
PLOTS...yellow on the map, yellow triangle signs at each corner of the area
ND G&F WMAs...red on the map, can't remember sign color?
ND State Land...blue on the map, markers are ? color
Also anything not posted is open (if you can find the land owner, asking is a nice touch though!)
And posted stuff should have the owner's tel# (we had VERY good luck when asking permission...100%)
Also, all 2-tracks are open to driving for scouting, etc.
If you don't have a plots guide...just look for the yellow triangle signs on the corners.
There's a pot hole over every rise.
I found that only 4-5 dekes were all I needed when I found a spot the birds wanted into.
Or no dekes at all.
Also, it's been real wet this year, the cattail edges are thick and deep!
Don't drop birds in them if you can help it...even the best dogs have trouble finding any crips.
Best of luck, wish I were up there with you.
