We chose to go to San Francisco because Mark's sister lives there and we adore her. An added bonus is that she lives in an incredible city and she was able to hook us up at a really great hotel with a discounted rate that made it possible for us to stay there. The hotel was across from the Ferry Building -- which, as a person who LOVES food, is my favorite spot in SF. It is also the waterfront - so I got to run along my favorite "trail" to the Golden Gate. HEAVEN.
