ON THIS DAY...
in 1881, the infamous gunfight at the OK Corral took place in Tombstone, AZ. Actually, the gunfight took place behind the OK Corral. Tombstone Town Marshal Virgil Earp, his deputies (and brothers) Wyatt and Morgan Earp, and Doc Holliday confronted Ike and Billy Clanton and Tom and Frank McLaury. The gunfight lasted thirty seconds and left Billy Clanton and the McLaurys dead. Virgil and Morgan Earp were both injured in the shootout.
To this day, there is still controversy over who shot first. The Discovery Channel did an installment of Unsolved History on the subject.
This site is probably the most complete on the web concerning Tombstone and the Earp/Clanton feud. It is maintained by Terry "Ike" Clanton, a descendant of the Clantons. It also contains a section on the ghosts of Tombstone to put you in a Halloween frame of mind.
Tombstone is one of my favorite movies. There is an excellent website about the movie here. It includes the Latin Duel Page, which translates the Latin phrases that Doc Holliday and Johnny Ringo traded in the Oriental saloon.
Another good Tombstone site to visit is the one mainatined by Big Nose Kate's Saloon, which was named for Doc Holliday's infamous girlfriend.
If you're interested in visiting Tombstone someday, you can see what there is to do there on the city's official website.
