I went to San Francisco yesterday with my Davis buddies, and we had a blast. We went to the Cheesecake Factory, a wonderful place, but we had to wait like an hour to get seating. So the moral of the lesson is, if you're planning on going to a really popular place, then make a reservation!
We had a lot of fun, though, with sightseeing, walking, and just socializing and catching up with each other. This may sound cheesy, but it is soo true: make the most of your life; explore!
