Having the experience of owning and running a coral reef aquarium (and frequenting this particular shop about once a week) - I was sad to hear it closed it's doors. Their reef display tank was always amazing. These pictures were taken from PetCo at Union Square (I also used to go there for my saltwater needs).
This park holds a special place in my heart because it has been like a backyard for me over the years. It is also named after the Secretary of State who negotiated the purchase of Alaska. There is even a Togo sculpture that reminds me of home. The bench strip doubles as a downtown runway.
