Pdog shooting; some of my best vacations ever. If you have the time, go by yourself. Study satellite imagery for active colonies. Go to a town near by, the feed mill, and ask for ranchers that allow shooting. If that doesn't work out move on. I viewed it as great vacation either way. Newcastle WY is a great place to start. Mill is in the south west part of town. Pines motel 5 stars. Dont bother with the government agencies, they are a waste of time and clearly don't want you shooting the rats. Ranchers hate them by the way. I would shoot 6 or 7 days, ware out a couple of 22-250 barrels and have a great time. Couple of beers and a picknick lunch, be sure to have some shade and a chair suitable for taking a nap.
One of my favorite subjects.
