Ferguson said that a potential escapee would have no place to hide. Richard Rubin, author of "Confederacy of Silence: A True Tale of the New Old South", said that MSP's environment is so inhospitable for escape that prisoners working in the fields are not chained to one another, and one overseer supervises each gang. A potential escapee could wander for days without leaving the MSP property.
