Our Story

Can you think of a better place to showcase the best vintage choppers and in the country? Didn’t think so. The Old Idaho State Penitentiary housed inmates from 1872-1973. It was first know as a Territorial Prison and was built in the Territory of Idaho in 1870. It was home to Harry Orchard who assassinated former Governor Frank Steunenberg in 1905. The prison holds a rich history of riots, murders, and executions. The Historical Sociaty has done an amazing job preserving this site and we honored to partner up with them in putting on a once in a lifetime event like this.

The Party at the Pen is an event centered around having a good time in a Historic venue that will add to the vintage American machinery on display throughout the grounds as well as inside the prison cell blocks.
