The town has struck gold again with HBO's show, which features a smoldering Sheriff Bullock and villainous Al Swearengen, owner of the sordid Gem Theater. Tourists stroll Main Street in search of landmarks like the Bullock Hotel (left) and the Gem (no longer standing). They seek out the side-by-side gravesites of the Old West's superstars, Wild Bill Hickok and Calamity Jane.

Hidden in pines, Sheriff Seth Bullock’s grave used to be mostly ignored. Not anymore.

Next: Meet Sheriff Bullock, now and then.
