Garden worker Carolyn F. Mack takes a short break from her duties February 17, 2012, at Medway Plantation in Goose Creek, S.C. Mack has worked at the plantation for the last 16 years, taking over a job previously held by her mother Janie Freeman who worked at the plantation for 22 years. In the South Carolina Lowcountry, more than a half-dozen antebellum plantations, which don't change hands often, are for sale. REUTERS/Randall Hill
