RICHMOND — A voracious curiosity about the world around her has driven Meghan St. John for as long as she can remember. It led her from Richmond, the tiny town of her upbringing, to the only slightly larger Middlebury, Vermont where she attended college. It pulled her to various domestic locales, from Sun Valley, Idaho (where she wrote for a now defunct art magazine) to Washington, DC (where she landed a gig at Nat Geo). This curiosity-fueled wanderlust took St. John to Paris and London, Ecuador and the Dominican Republic, sprawling cities where she lived, in total, for a decade. Today, after a dozen years teaching English at Monument Mountain Regional High School (her alma mater), curiosity has led her to the curation and production of podcasts, much to the delight of local listeners.
