It's hard to find mom and pop stores anymore. In Green Hills, the Donut Den has been a mainstay in the South Nashville community. The classic "Donut Den" neon sign has been down due to renovation on the shopping center. Owner Norman Fox let the public vote between two signs, the old or an updated version.  The results show customers want the old sign back.  The shopping center will be glad to respond to the vote of loyal fans. Thanks, Nashville. Channel 4 reports...
