Okay, so right now the plan is to go to Six Flags, New Jersey, find a hotel, then drive to Boston and wander around, then drive up to Maine for the lobster bake (
complete route here).
I'm trying to find something fun/random to do between NJ and MA, but with little luck. The Mark Twain House/Museum looks pretty cool though I don't know if AD and V-man will be down for all that educating. I was thinking of Ben & Jerry's but they are in Vermont which is a teensy bit of a detour. We're not really beach people.
Ah well, if worse comes to worse, wandering Boston is always entertaining. Lots of random shops and food and such.
