Been out to South Dakota the third week in May. Dogs are pretty small, maybe only 4 weeks old...pretty small targets. This year it will be June 10th. Besides, it can rain, windy or be cold. If you are on a budget like me, I don't like to get blown away in my tent! The later you go, the more you have to be aware of Rattle snakes. I carry my Bond Arms .45/.410 and AR15. The season does not open until June sometime on public land. License is still $35.00 unless you go to the Rosebud. They charge $150.00 manditory.. for the guide. Bottom line...they don't want paleface on their turf.
