I tried to make a list of all the States I've visited but there are some where I was there for a week or more, some I go to all the time, and some I really just transited (on the train or driving through.) So, I marked them appropriately.
Yes - I've been more than once, for multiple reasons.
Transit - passed through, either driving or changing planes
Train - I was on Amtrak and went through the State
Cruise - I was on a cruise
Layover - I changed planes there
No - I haven't been there at all
