I heard back from my dad's cousin and it looks like I can stay at her house in Falmouth. It's on a salt marsh that I really want to shoot, too (in case anyone else might like that idea). At this point, either day is fine. I'm thinking of driving up on Wed or Thurs and back to PA on Mon or Tues or maybe even Wed. I'm flexible! And I can't wait!!!!!!!!! And, yes, it's a 12 hour or so drive - so the weather better make it worth it!
