First was an 90 minute fast ferry service across Boston Harbour from Ptown to Boston.
Then a four hour train journey from Boston down the coast to New York's Penn Station.
Then riding the E train subway to Jamaica station.
Then the skytrain to JFK Terminal 7.
Then (after a very pleasant hour or three in the Concorde lounge) an 8 hour First Class overnight flight on BA116 back to Heathrow.
As dawn in the UK broke, we completed the final leg of our return journey - the fun of joining the rush hour commute!
A long journey, true, but we pretty much laughed all the way.
