I love knitting in public... I recently had to attend a two day conference for work - took my knitting with me. I got something accomplished and during wait times wasn't bored out of my mind. I have also found that it draws other knitters - and have found that more people knit than I knew. At work, we are thinking about starting our own UFO club (unfiinshed objects) and make it a social not work releated activity.
BTW - I'm teaching my almost 10yr old son how to knit. He knitted his first swatch last night!!! He enjoyed it and I had to fight with him to go to bed - he wanted to keep knitting.
Knitting on the Road - I showed him your blog so that he could see that men do knit. He liked the booties
