I've been a ghost story writer for most of my career, in fact, my first online publications were via The Shadowlands though I never thought of those tidbits as building a portfolio - otherwise I would have spent a little more time on them, yeesh. ;) And while zombies occupy my time now, ghosts are never that far from my writing schedule. As such, I love to take my girls to local graveyards for inspiration. Not only for the history they provide and the connection to the community but also for the amazing art found on the stones. My early days as an archaeologist and historian focused on burial customs and the folklore surrounding death plus the symbols left behind to comfort the living so it also takes me back to my roots.
My current short story WIP deals with ghosts, pirates and betrayal. After this week, don't be surprised if a soldier pops in as well. ;)
