I promised my friend George, who lives in Denver, that I will never mention all of the wild and decadent sex parties that are held in caves somewhere in the Rocky mountains...
Yes there is. I know the secret question to ask too. Just go to Denver and ask people on the streets who you think are in the know, "Do you know where the Colorado Cockies play?" Someone should give you the address...
In the 1880s there used to be alot of mining in Colorado. I would suggest searching the many defunct mine shafts until you find what you're looking for.
