Mother Jones magazine recently published a piece where they interviewed documentary filmmaker Alexander Perlman on his documentary "Lot Lizards" that provides a candid look at truck stop prostitution. The film's title comes from trucker slang for these prostitutes.

Hopefully this film will help publicize the problem of truck stop related prostitution. Earlier this year, Mother Jones detailed an innovative program by Dallas, TX Police to help truck stop prostitutes leave business by helping them with counseling and rehab.
