The Hallmark Channel movie “Christmas in Homestead” that used Dahlonega as a backdrop is slated to air at 8 p.m. on Thanksgiving. But the city of Dahlonega already has much to be thankful for in terms of the approximately $375,000 estimated economic impact. “This has been the longest project we’ve had for filming, so in that sense I would say it was the most profitable or the most economic impact,” said Rebecca Shirley, the city’s downtown development authority director.
