The last three years (5 trips) I have used Jon Wik at LWR Ranch outside Martin, SD. He runs a good operation. Not the cheapest, but you will eat & sleep well (3 Meals/day), and shoot at a lot of p-dogs. http://www.lwrranch.com/
You pay to shoot pdogs? Come to Watford City N.Dak. and you can shoot all you want for free. We have miles of pdog towns bordering the north unit of the Roosevelt Park on federal grassland. Stay in Watford and it is a 20 minute drive away.
