You can knit in the car? I'm so jealous. I suffer terribly from motion sickness. It's hard for me to read a map sometimes, so I make a list of highway and exit numbers. We went to see The Bourne Identity and I had to sit with my head down not looking at the screen- a "steadicam" is the worst misnomer ever. Can't go to the planetarium, either.
Blowing Rock is a great place. There are some really good fiber artists in that area. It's also a hotbed area for studio potters.
