One of my most favorite places to go on campus at my school is the Japanese Gardens. It's small and quaint and very peaceful and there are so many Koi swimming in the pond all you see is a giant fish mass slowly making its way around. There's one giant gold Koi that I swear looks like it came right out of a fairy tale. If you are ever in the area you should check it out.
Here's a few pictures I took while doing some sketching and watercolor painting around the pond. The last one is of a quick watercolor study.
