Day 4: Tombstone, AZ->Las Cruces, NM
Tombstone is fun. Lots of old-west people wander an old-west town having staged shootouts and selling hats to tourists. I overheard a grizzled cowboy trying to hire a gunfighter...over his cellphone. (Gunfighting apparently pays $55/day plus tips if you do three shows a day.) No cars are allowed on the main drag, only horses and buggies.
Bisbee, AZ is full of beautiful old brick buildings winding up the side of a hill. The copper mine is scary-large, and the landscape coming north from Douglas, Arizona is spectacular.
