We have gone to various ghost towns. The website showing the locations state by state is poorly organized for any sort of planning. The entries are not prioritized in any way. You have to dig down only to often find that there is nothing there except a foundation for one building. Not worth the effort to drive to. But doing a planned trip to the substantial ghost towns would be interesting.
As for high quality ghost towns, the one on the River rd in Big Bend NP was good with quite a few buildings still standing. Dillon MT was an accidental find for us. We were just randomly exploring the backcountry when we stumbled across it. It had a lot of standing building, some semi-standing. Maybe 12-15 and a large mine structure. It's off I-15 just north of the state line.
