I flew there a few years ago in a Super Cub. I, too, wouldn't mind a relocation to that area. A couple options close (Rigby, Blackfoot), but from my experience the Idaho Falls Regional was incredibly GA friendly. My info is useless as I don't have any info on hangar rent, etc, but the primary FBO, AeroMark, is one of the best FBO experiences I've ever had. I am sure they would help you out if looking in the area.
