Wyoming Territorial Prison you can visit April through October. You may see only one 1890's inmate still there (wink). Is it convenient the place is not closed until the first of November?

This is a historical place with a walking tour, and along the way, interesting literature is offered. Information about the early days includes how the temperature of the cells was about 10 degrees warmer than outside, until heating was later improved.

One story posted is about Julius Greenwelch, who had a heart attack and died, as did his dream of a successful cigar business. Until the 1890's, he’d been a cigar maker who traveled Wyoming selling his high quality cigars. He would stop at a bordello in Evanston. One trip ended early, when he was shocked to see his wife, Jennie, who had started working at the bordello, herself. If it was for spending money, she also got back at her husband for infidelity. Well, Julius over-reacted, and shot Jennie dead on the spot. 

That equaled life at The Wyoming Territorial Prison, where he had talked officials into letting him set up an incarcerated cigar making operation. Of course, some of the sales of cigars would go to the state.

After Julius was gone, it was believed a later noisy renovation of the prison (and removal of his cell) "awakened" his spirit, still wanting to make cigars for profit in prison. The smell of cigar smoke sometimes wafts out of the north wing. Workers around the buildings sometimes found their hammers, drills, and saws missing, often finding them in odd places.

Hauntedhouses.com says Julius is just getting a few laughs - letting tourists, and staff know he is still there - serving his time even in his after-life. 

He only makes himself know with a group less then four people and when people are TRYING to sleep.  Only a few have seen him in complete form without any devices.
