Argh tell me about it! I found Logan Airport really really intimidating! Those guys that go up and down the line asking you your business, where you're staying, how you're getting from the airport etc! It was my first time in the States and I was on my own so didn't know what to expect at all!
The only other places I'd travelled by plane had been Greece, Cyprus, Spain and Norway who are all really relaxed so I found it really scary! Got to agree with you on the area though - it's gorgeous. I went in October too so it was particularly beautiful, they've got great trees!
