I have to go to San Francisco on business next week. I have training for 2 days and then am staying for the rest of the weekend on my own. So, my question is (for the very few who might actually still be reading since I have been neglecting my blog), what are the places I can't miss... yarn stores or otherwise. I have never even been to California, so I don't know anything about the area. If anyone has ideas, leave me a comment.
