During a June heat wave in Boise, Idaho, ANTIQUES ROADSHOW visited the Old Idaho Penitentiary, (known as "The Old Pen" to locals) to learn more about law enforcement collectibles with host Mark L. Walberg and expert Gary Piattoni. The Old Pen opened in 1872 and remained open for 101 years. Over that period of time, it received over 13,000 inmates, with a maximum population of over 600 inmates. The "Old Pen" was closed in 1973 after a series of inmate riots over living conditions.
