Reply #3: I used to live 2 miles from the Chino Men's Prison ... [View All]

Here is a blurb at the prison website:

Special Historical Notes

When it opened as California's third correctional institution in 1941, CIM was unique in the field of penology because it was known as the "prison without walls." The only “security” fence around the facility units was a five-strand barbwire livestock fence, intended mainly to keep the dairy cows from wandering through the living areas. CIM has since increased security to meet the challenges a vastly different inmate population requires. While no longer the “prison without walls” CIM does have the largest level one facility in the Department. In June 2006 CIM will proudly celebrate 65 years of continuous and faithful service to the People and the State of California.

CIM is surrounded by the Chino Dairy Preserve .... It looks like a military housing unit from the outside .... but it was apparently designed from the start as a correctional facility ...

This is the prison that Kevin Cooper escaped from and killed 4 in a local household .. a young boy escaped by hiding ....
