You guys are lucky. I think the more south I went was Buffalo... and it was only a "fly-by". I never really visited the states.
However, I don't want to go too much southern... The more southern you get, the bigger the bugs get. I don't want to wake-up with a six inches large spyder on my chest.
At least I saw Canada from Toronto to Halifax... I wish to go to Vancouver somedays...
May be even plan a trip to the UK... Visit London, Dover, Portsmouth, Plymouth, go up a little then take the ferry to Ireland, visit a little then go back on "the big Island", go north to Scotland and then go back south by following the east coast. Ahhhhhh... *The* dream.
