I knew the US was big but did not appreciate it until I went there last year, one four hour hop on an internal flight. Friends were asking why it took me a day to get most of the way to where I wanted to go (flight times were not helpful).
I tell little white lie, I did drive from Vancouver to Calgary but that was a while ago and the memory fogs. Our last visit (see above, first proper visit), we are asked if it is our first visit. I reply I went there for a day trip once. I get an incredulous look.
