Lots of people stumbled onto Margaret’s Grocery by accident, taking the cutoff from Highway 61 into Vicksburg, Miss. It was an incredible site and its maker, the Rev. H.D. Dennis, was just as incredible (and voluble). Bruce West not only stopped, he developed a continuing relationship with Dennis and his wife, the site’s eponymous Margaret. The book documents the evolution of the environment, from his early encounter to its decay after the couple had died. West’s photos and text gives the site, and the couple, their due.
