dogdr, I have never hunted SD, but I have been to ND a few times. My old man has been to SD at least 10 times, but got sick of the #of people, so we started to go to ND. There are not as many birds but they have lots of public land and lots of the farmers have let us hunt for free (hunting for free, that is starting to be a thing of the past), we just left them a few birds of dinner. We never shoot no were nere 160 birds but we have a great time, and for us it is alot closer (from Upper MI). It is all about what ya want from a hunt, lots of birds and lots of people or good numbers of birds and vary few people, some days we didnt see another hunter.
I would love to go to SD some day just to say that I have.
