Query: Has the author ever VISITED San Francisco?

I keep guidebooks on hand for my friends when they visit me in the Bay Area. This is the worst book I've ever mistakenly purchased by far. It's so bad that is as if the author wrote a book about things her Aunt Sally told her about a trip to SF in 1953. Clueless, yet humorous for natives. (She suggests a visit to some annual rodeo out here, and I don't think she meant it for cruising.) Do not for any reason (other than a laugh) buy this book.
