Actually I'm pretty sure there are clinics in Powell, Sheridan and Riverton Wyo. There is also a larger VA hospital in Billings Mt.For this next phase of life rural has its benifits and you have listed them well.
My only real concern is the proximity to a VA clinic. I'm 99% independant, but that 1% is tethered to a visit every year or so.
Plus the closer it is, the more benefits I can have.
