In a sculpture garden in Maryland, Kevin created a series of petroglyphs, each rock meant to highlight different aspects of local life. His carvings of fish, boats, crabs and the iconic upside down astronaut showcase the lives of commercial fishery, sport fishery and the Patuxent Naval Air Station, where they train astronauts and fly experimental aircraft. The pieces are meant to reflect the Chesapeake Bay and Watershed, in order to do that boulders were collected from the watershed itself and brought onto the site.
