On that note, I emailed my friend David, who goes into NYC quite often, if he ever takes day trips. He does quite often, he said, taking the train from New Haven or Milford. So, I could easily take a train from Hartford. I'm going to quiz him more.
I'm fairly certain that if I can get my keister there once, I can do it again. I picked up "The Unofficial Guide to New York City" and I intend to wear out its pages. That series of books is the main reason I know so much about Walt Disney World.
