gold miner
n.— «Every summer, it seems, more jobs fall to what residents deride as “gold miners”—mainlanders who commute to the island by ferry; Mrs. Luce, for example, said she had long relied on locals but now has a gardener from off-island.» —“An Enclave Shared by Blue Blood and Blue Collar” by Corey Kilgannon in Fishers Island, New York New York Times July 31, 2007.
