Boot Hill (or Boothill) is the name for any number of cemeteries, chiefly in the American West. During the 19th century it was a common name for the burial grounds of gunfighters, or those who "died with their boots on" (i.e., violently). Also, Boot Hill graves were made for people who died in a strange town without assets for a funeral, known more formally as paupers' graves. -Wiki
One of the most famous Boothill cemeteries is located in Tombstone, Arizona. It holds a lot of famous Wild West people. I don't really like to describe a cemetery as "entertaining", but this one certainly was. Check out the slide show. Read the grave stones!
Geocachers: There is a Mystery Cache there... which I must have screwed up the numbers on, cause I didn't find it. ;-)
