I ride from Bellows Falls (or Brattleboro) Vermont down to New York or Philadelphia (or DC) a few times a year.  (sometimes I take the bus instead).  Some of these trips have been to visit a (now ex) girlfriend.  Others have been for work or church business of one sort or another.

I went to Chicago a month or so ago via the lake shore - for a rail advocates meeting.  A few years ago I went across the country via Lake Shore and California Zephyr.  That was to cover a writing assignment.  I haven't flown domestically since then.  (My driving has all been short-distance, except 2 trips to a friend in Halifax NS - not gracefully rail accessible and one driving trip to Virginia for a writing assignment)

I have traveled in various places by train in Europe (to visit friends and be a touriest).  My most recent trip, I wasn't very adventuresome and traveled around London by train on various routes and companies, and ditto for Paris (took the bus in between) and that’s it.

I travel on commuter trains from time to time as well - I was on the MBTA and Metra (Chicago) recently, SEPTA last summer.

It would be nice to travel more, but I can't afford it.
