For me it was the fact that there was absolutely nowhere to stow even the smallest of my bags when catching it out of Heathrow. I had to stand with two suitcases and two carry-ons in a crush of people. The carriages are so poorly designed it boggles my mind - if the seats were just half a foot higher off the ground I could have put my suitcases under them and I wouldn't have been in so many people's way.

Scotland is pretty awesome. And pretty. Today on the train I saw a castle out my window.
