Today was my fun day in San Diego. I took my breakfast to the beach and enjoyed the peace and quiet for a while. I then went up the the Birch Aquarium. It's a small aquarium, but the had some cool exhibits. After the tour of the aquarium I went up to the harbor and took a tour of the USS Midway, which was very interesting. I wasn't sure where I was going, so I had to walk about 5 blocks to get there. At least I got some cardio in.
