Nantucket was more than shops, and shops, and shops, and shops. It was the home of "kettle ponds", lovely little lakes formed by glaciers. These were not major attractions and it took us a long day of bike riding to locate several, but they were worth it.
On the way we wandered the beach and found a gang of Labrador retreivers bobing in the surf. On closer inspection, they were more accurately identified as seals, but why they were staring at us was unknown.
They heart of the island was found in the whaling museum and its whale skeleton, lectures, and wonderful exhibit.
