I took these small sketch books on a trip to San Diego. I had a long lay over at Kansas City airport, that is the book on the right.
On the left is from the San Diego Zoo.
Right: blank, nothing, white rabbit caught in a snowstorm...
Left: Francois' Langurs are very interesting small primates, especially what looks like mutton chops or a full beard. The pose of the one in the tree, with his leg propped up, was so relaxed and lazily scratched his leg part of the time I drew this.
