A few years ago when I was in college I did a summer program at Cambridge aimed specifically at Americans and Canadians, and my year it was all Americans and one Australian. We ended the program with a week in Wessex, and on the last day as we all piled onto the bus in Salisbury (or Bath? I canât remember), the professors went to the front to warn us that we wouldnât be making any stops unless absolutely necessary. Weâre headed to Heathrow to drop off anyone flying off the same day, then back to Cambridge.
âAll right, itâs going to be a long bus ride, so make sure youâre prepared for that.â
We all brace ourselves. A long bus ride? How long? Weâre Americans; a long bus ride for us is a minimum of six hours with the double digits perfectly plausible. We can handle a twelve hour bus ride as long as we get a bathroom break.
The answer.  âTwo hours.â
