Retired coach Duke Oxford and his wife Toni Oxford could be tending to Duke's new work of selling artificial turf or maybe even taking some time to just enjoy themselves. Instead, they've created "Mel's Diner" (the name taken from the old TV series, "Alice.") This diner's now a mobile unit, staffed by lots of volunteers, and providing casseroles, sandwiches, fruit and desserts to the city of Charlotte's neediest. But mostly it's Duke and Toni, working round the clock, paying bills from their own modest resources, enlisting kids to elders in being their hungry neighbors' keepers. Keep up with them, if you can, at the Mel's Diner website.
