Shelton Drum’s comic shop in Elizabeth, Heroes Aren’t Hard to Find, has filled the city’s nerdy niche for 34 years. In 1982, Drum took his small-scale convention, Charlotte Mini-Con, and transformed it into HeroesCon, a city institution that now brings thousands of fans from across the country. Every year, high-profile comic creators, retailers, fanboys, and cape-clad cosplayers pack the Charlotte Convention Center.
