Have planned a 3300 mile, ten day run, from South Florida to Meredith, New Hampshire over the Memorial Day holiday, then across Vermont, upstate New York, central Pennsylvania, Washington DC and back south to home. Haven't visited the area in the past twenty years so I'm sure things have changed a lot since then. I was told the black flies are bad in New England during April, May, June. Any advice from the locals? What special places to visit? To eat?
