We had a BOGO free coupon for the Mystic Aquarium so we ran up and visited for a few hours. It was a touch chilly, but that translated into smaller crowds. Honestly, I think the animals preferred it a little cooler. They were all swimming around and playing (except for a few lazy sharks). Anna watched whales go by, penguins eating, and sea lions roaring. We got to see all sorts of fish, eels, sharks, rays, and other fun water life. We had a blast!
