The day the brand new Mason County, Washington jail opened in 1985, it was already full. The previous jail on the top floor of the courthouse held just over 40 inmates. The new facility wasn't much bigger. Nearly 35 years later, the one-story cinder block jail located in the town of Shelton now holds about 90 inmates on any given day. A few years back, as many as 150 people were crowded into the facility.
