The Iron Horse Saloon (north side of Durango Co.) had the best free chili and coldest beer in the San Juans. The women weren't bad looking either.
Last time I was in Deadwood, in the fall, discovered that there are two saloons called #10. One is restored, but not in the correct location? The other claimed to be the original. Opposite sides of main street, within sight of each other. So as with many old locations, different stories exist. Beer was fine in both!
The International in Austin NV (and you can drive the Loneliest Road in America.)
The bar came from England to a place in San Francisco and then out there. Barely occupied by folks, Austin is a neat little town in the middle of nowhere.
Of course there is also the oldest bar in NV in Genoa at the foothills of the Sierras and the entire town of Virginia City.
Another vote for the Buckhorn Bar in Laramie.. I was in a number of squabbles in that place. Both before I wore a badge and after I started wearing one.
If he was ramrodding one of them Big Boys over the summit, he was the bull of the woods that's for sure.
I can still remember hearing the whistles blowing on those old boys as they headed west out of Cheyenne..
Look for the tiny town of Fairplay on State Highway 9. It's on the other side of Hoosier Pass from Breckenridge, CO.
+1 for the bar at the old Menger Hotel bar next to the Alamo.
Also in downtown San Antonio you can find the Buckhorn Saloon (and museum). It still has some of the furniture and feel from the 1880's. It has been moved several times, including many years at the old Lone Star Brewery. You can walk into the bar and have a drink, but you have to pay admission to see the museum part.
Can you imagine back then walking into a general store, middle of nowhere, and trying out a Colt SAA???? That would have been such advanced technology.
