25 miles from Rock Creek is Old Works (Nicklaus & Olenoski). Fun, inexpensive, and in good shape, if not an elite trophy course. Front side is great and after the first two holes on the back one could argue it loses some steam. It’s also as big and brawny as you want at 7,700 yards from the tips. Perhaps the most interesting aspect is sociological in its role of turning an industrial wasteland into golf course and thus really helping (if not saving) a dying old mining town. You could easily do both in a day. Personally, I don’t know of a greater contrast in architectural styles so close together. Then again, you could just go around RCCC another time. When we were there a few days before their club championship, we were the only group on the course that day.
A swing down into Idaho to Huntsman Springs (Kidd) on the Idaho side of the Tetons and through the pass to Jackson Hole 35 miles away might be an amusing way to get to SLC, a pretty good and inexspensive golf town, as well. This entire route might be 500 miles of very attractive country with lots of good golf from which to choose. And more than a few hot springs to wash your pits (like Fairmont 7 miles from Old Works). Out West, 500 miles a day is child's play.
