I grew up in Gillette and did my nursing residency at the hospital there--Campbell County Memorial Hospital. I LOVED IT. It's 2 hours away from Rapid City--not sure what part of SD your family is in. However, I LOVED the hospital in Gillette--your problem might be housing, however.

However, it's a GREAT facility, they are undergoing a big expansion...but housing is a must if you plan to move there. They ARE building tons of apartment complexes and homes, but it is still in a housing crunch. I would definitely recommend CCMH if you want to live in Wyoming and have proximity to SD!
