It’s the last week of Christmas break. If you’ve heard about how bored the kids are, today and tomorrow are the last days to see seven race cars, all driven by Mario Andretti, at The National Sprint Car Hall of Fame and Museum. The Knoxville Rec Center is open as well, for open swim from 1 to 4 today and from 1 to 3 Tuesday. And the Knoxville’s Public Library is open as well, for regular hours today, and closing at 3 on Tuesday. There are books, DVDs and the new Freegal program is available for downloading mp3 selections if you got a new e-reader for Christmas.
