Duke didn't play Davidson in 1980.
Duke did play Davidson at Charlotte on 1-2-79. I don't remember that one. But I do remember a game against Louisville the following month where it snowed in copious amounts and the Charlotte Coliseum was quite empty.
I'm not especially worried about this system. If it gets bad, I've used the southern route from Charlotte to Raleigh in the past, with no problems.
As an aside, I really appreciate the gibes from people who don't have enough sense to get out of Vermont.
As an aside 2, the Duke fan base filled the Belk Bowl last year on a night when the wind chill had to have been in the 20s.
