The town of Chester, Vermont is just lovely; all the buildings are made of local grey stone. If you like living history, Plimoth Plantation is well worth a visit while you're on the Cape, and the island of Nantucket is filled with photo ops. Too bad you aren't coming a little later in the autumn; the first 2 weeks of October are just a riot of outrageous foliage, especially in the more rural areas and the many pretty towns with Colonial-era buildings...those few glorious weeks are amongst the major reasons I live in New England.
