My wife was talking about us moving back to South Dakota after we retire. We spent a lot of time there when I was on active duty. Much lower property taxes, lower cost of living, very friendly 2A laws, beautiful part of the country as we were minutes from Mt Rushmore. The winters can be hell, but it tends to keep a lot of the riff-raff out. The state is the size of PA with less than a million people total. Nice place to make the retirement dollars stretch further if things don't get any better here.
PA state ranges can attract an undesirable element at times. Look for gun club ranges all over the NE PA area. Have one just across the DWG area where membership is the same price (East Bangor Sportsman's Assn,). In fact they have quite a few NJ members. Most will ask for copy of your FID card as they require signed forms for background checks of PA applicants.
