Tom.............If you're in the Tombstone area, you might want to check out Charleston/Fairbank , Brunckows Cabin, or the original site of the Clanton Ranch off of Escapule Rd. If you are heading south from Sedona you can detour over to the Bradshaw Mtns. where there's a few old mining towns (Tip Top, etc.) But I don't know if you can get to most of these anymore with a 2WD car. There are websites that have maps of ghost towns close to where you are going (Maybe even this one) that will give you road conditions and travel time. I think that might be your best bet. Have fun and enjoy your time in Arizona.
