When I was younger and lived in the Boston area, the way I got around was street running trains that, if you were going a certain way, went underground. Today I wouldn’t like the hustle and bustle these modes of travel would bring.
I flew on an airplane just once and that is all I will say about that.
I would have to say that my preferred mode of travel would either be by car or Greyhound bus. I say this because my best travel memories were spent sitting in these land vehicles.
Every road trip via car or Greyhound bus has always been an adventure. Meeting new people along the way is always fun. And traveling at ground level allows for great sight-seeing.
