My apologies to Carol for the picture quality - I had to use my geeky smartphone. I had fun talking to Carol. She is an interesting and delightful woman... and her sock was beautiful too.
So fellow knitters, the end of the story is that Carol knitted for 3 days in the conference and no one vilified her, spit on her, or asked her to pack up her knitting and beat it. If Carol can knit unharmed surrounded by geeks, so can you!
