The covers of all three books in my Florida Folk Magic Series feature a railroad crossing usually with bulkhead flatcars on it. First, the Apalachicola Northern Railway operated in the Florida Panhandle county where my stories are set. It still exists today as a shortline called AN Railway, operating between Chattachochee, Florida and Port St. Joe, Florida on the gulf coast. In the 1950s, as now, the line carried wood products, frequently in bulkhead flatcars.
The second reason for the cover picture refers to the age-old belief–which became part of hoodoo–that crossroads and crossings were dangerous places over and above the possibility for wrecks. Either bandits were there or spirits were there. So, great care had to be taken.
Some of my railroad references in the books come from the fact that I was a volunteer at a Georgia railway museum that had operating trains as well as many historic examples of older operating equipment, including a bulkhead flat. As you can see from the photo, the bulkheads at each end of the flatcar helped contain the logs or other materials being hauled. In a part of the country where lumber and other wood products were important, these cars were a natural to mention in the books.
