Report New England in September in Travel Posted September 8 · Edited September 8 by Mr. Camper Normandy Farms in Foxboro is your best bet for the Boston area. Cherry Hill Park in College Park, MD is great for D.C. Liberty Harbor in Jersey City is basically a parking lot but it will serve your needs as it's all about Location, Location, Location. We stayed at Philadelphia South/ Clarksboro KOA and finally, Bar Harbor/Oceanside KOA for Maine. We've stayed at those places. I hate to bring this up but be wary if the government shuts down without approving a debt extension as you may have some national parks that will be closed. Just have a good Plan B in case it happens.
