Definitely Casper.
Evanston has it's points....it's near SLC, Utah and right on I-80.
However, Casper is probably your best option. We're about 60K people, on I-25, central in Wyoming.....we are a regional trauma center, with (dare I say) the top physicians and nurses (and ancillary staff) in the state.
There is TONS of culture here (if you know where to look). Eleven museums from art to science to WWII/vets. The indoor football league has a team here, we have the Casper Ghosts (which were formerly the Casper Rockies) semi-pro baseball...the Casper Events Center is host to TONS of events (high school sports, concerts, plays, symphonies, etc). Excellent golf courses, great fishing, near Lake Alcova (boating), at the base of Casper Mountain (camping, skiing-both x-country and downhill, hiking, etc).
There are numerous nursing homes/assisted-living facilities.
Of course, we have downfalls as well....wind, not enough primary healthcare providers (usually because Wyoming doesn't have tort reform and the MD's can't afford malpractice insurance). But the people are friendly, well-educated, and very welcoming.
We also have some of the greatest restaurants....Italian, Chinese, Thai, as well as the great all-American greasy burgers, BBQ, mom/pop shops...
Hope you make the right choice for you and your family!
