Botanical Gardens at Balboa Park

In the afternoon, my parents and I went to Balboa Park. The park is enormous. It contains a handful of museums, the zoo, maybe a half dozen gardens, 20-some international houses, an outdoor concert area for a giant organ, and I think there's a few trees and grassy fields in there too. Out of all these options, we chose to visit the botanical gardens (one of the few free things and I highly recommend it!), and we unintentionally caught an organ concert while I refreshed myself with some ice cream.
