In reality, Tombstone was a highly dangerous, nasty place. We went to the Boothill Cemetery, where 250 people are buried. Most of them died awful deaths--found in mine shafts with bullet holes, hanged, lynched, suicides, stoned to death.
The OK Corral is now completely enclosed with bleachers, where they charge you to watch a fake gun battle of a real shoot-out that lasted a total of 30 seconds.
The most worthwhile thing in the town is the old Courthouse, now run as an Arizona state park--a very well done museum.
