Oh, the things you miss at sea. Shopping, anyone? We're in transit, on our way to the Sea of Cortez and Guaymas Basin, and there is more than enough to keep busy with. Alvin pilot Mark Spear opens the Atlantis/Alvin t-shirt shop just for one hour, and the holiday shopping season is open. I pick up a few shirts, including a long-sleeved red one for myself.
