Their tidy Creole cottage cafe in the small riverfront town of Wallace lies yards from property their great-grandparents bought more than a century ago. It’s a historic area the sisters have dedicated themselves to keeping free of the heavy industry that lines the opposite shore of the Mississippi River. “We have all these little pockets of free towns surrounding these plantation cane fields.
