I had a really nice day of letterboxing in Golden Gate Park. First we found the Tribute to the Japan Earthquake series, and then we found the Stow Lake Microbox series. We had to hunt pretty thoroughly for the Andy Goldsworthy sculpture outside the De Young that was the starting point of the Tribute clue. The De Young is my favorite art museum. It was closed today but there is loads to look at in the Garden of Enchantment.
