With 11 people it's hard to do anything or go anywhere very fast. Therefore, my suggestion to anyone in a similar situation is to take the things you want to do, and cut it in half; and that should get you to a more realistic plan of action. This is not me complaining, we were plenty busy. I just think you should know that there is so much to do in San Diego that you will want to prioritize the things you'd like to do and see.
We walked so much that at one point I thought it possible for my legs to fall off. Thankfully, the zoo had a 40 minute bus tour that I was happy to ride, as well as a Skyfari (see above) that hoisted you high in the air and took you from the front to the back of the zoo in mere minutes. Not long enough, if you ask me. So in the name of "zoo orientation" I happily rested my bones. And since our tour was full of animals (as you'd expect) the only exhibit that required any real effort to go see was the panda. And let me tell you, it's cute. Unfortunately I can't tell you its name, if it was a male or female, how old or big it is, how many other pandas live at the zoo...basically, I can tell you nothing. I was too busy vying for a spot to snap this picture. Did I mention how cute it is?
Annnnnnnd, it's currently snowing! I hope it snows and snows and snows because our crops are so dry. Thirsty thirsty thirsty.
