Getting there:
From Boston, take Interstate 95 northbound to Exit 7 Market Street/Historic Sites, last of four Portsmouth exits and last New Hampshire exit before highway crosses Piscataqua River into Maine. Toll at Exeter/Hampton, N.H., is $1 each way. Traffic delays are common on I-95 in the summer, as crowds head for the beaches and the mountains.
