Old Idaho Penitentiary off Warmsprings Road in Boise. Call me weird, but I enjoy visiting the Old Pen. Rumored to be haunted, it is an eerie place full of history. It was built by the inmates from local sandstone from Table Rock. Stops along the tour include the women's ward, solitary confinement, the gallows, death row, general population, the laundry/shower room (...shudder...) and exhibits on tattoos and weaponry.
