Game wardens can come an search freezers/houses etc at their free will if they so choose in SD. I personally have no problem with this law. I have nothing to hide, so let them come if they want.

As for shooting deer an stuff without a license that information can be found in your states hunting handbook or the states Game and Fish website. In South Dakota landowners do not need a license if they are hunting small game on their land, if they choose to hunt waterfowl on their land they need to buy the Federal stamp. Deer licenses in our state are done lottery style, so landowners might not even draw a buck tag, but there is a new landowner/operator license that allows you to pick one of your quarter sections, and you can only hunt on that land and shoot a deer (buck or doe).
