Umm there will be pockets here and there. You can not walk the road ditch where any signs are present. So that is one thing. But unless it changed you can walk land that is not posted. Which is a bad idea. The reason most posted land. If it is not posted then walking the road side good spot seems to never cause a rukus. But even if it is not posted, I will not set foot on someone elses land with out asking. do not be stopped by posted land, ask any way. Many do not even hunt, but they put up the signs because of the stupid laws ND did. Believe me when I say many have told me they hate posting and spending the doe and time on stupid signs. But , they just want to know who where and what is going on out on their land. Anywhere from the James river to the Missouri along the SD border you can find birds. But closer to the Missouri is better.
