During the Frog Days of Summer, when the McSheas head off on vacation to Cape Cod, we always make sure we sign up for a whale watch. No, it's not a tourist trap or gimmick like those glass-bottom boats, but it's a fascinating way to get up close and almost personal with these incredible mammals...whales!

Check out this video of humpback whales shot by a Dolphin Fleet tour boat off the coast of Provincetown, Cape Cod. That's the tour boat fleet we always sign up for.
