Dec. 22. By Caroline Stevens. If you’re feeling a little Grinchy this holiday season, the cure may be some good news from Whoville—or, rather, Smithville—where a Christmas miracle happened for Cheryl Knox on Thursday. She had been heating her home, where she’s lived for years, with space heaters. Thanks to a committee of local elves headed up by Austin Helms of NuBlue Plumbing, who donated his labor, the Peninsula Community Foundation and the Lake Norman Community Development Corp.—which paid $2,600 for the new HVAC system, Knox will be warm and cozy this Christmas.
