This cocktail has been on the menu of Denver's Famous Fort Restaurant since 1963. The "saddle leather" is a stick of buffalo or beef jerky garnishing each glass.
Dampen each glass rim and press the rims in salt. Pour all ingredients over ice cubes in 4 highball glasses. Stir well. Garnish with jerky and serve.
Carbonated Grapefruit Juice makes this a special treat.
