You mentioned SLC and the communities south of SLC. Try the southern end of the state. St.George has a good airport and medical services. Actually anywhere from Cedar City to St. George has good weather, golfing biking and two ski resorts. Brian Head and Mt. Charleston, NV. There are two colleges, the Shakespeare Festival, the south end of the Wasatch MT range, good fishing and boating. Two hours to Las Vegas. Unfortunately a ton of Southern CA retirees have found it.
