Due to special programming on PBS, UNC-TV will air North Carolina Weekend on a different schedule this week: Thursday at 7:30 pm, Friday/Saturday at midnight and on Saturday at 10 a.m. For this week’s show, celebrate Mountain Heritage Day in Cullowhee. Get back to nature at Elk Knob State Park in Todd. Take in the National Model A Tour event in Cary. Step back in time at Dellinger’s Mill in Bakersville. And the “House Special” samples the fare at The Friendly Market in Morehead City. (Please note: listings are subject to change.) North Carolina Weekend is underwritten by the N.C. Division of Tourism. In addition, UNC-TV has made recent editions of North Carolina Weekend available online.
