That was quite a long day, not much less than mine. I left Tarragona on the 7:00 bus, flight at 10 to JFK, arrived early at 12:25, picked up rental car and sailed home in light traffic at 15:35 local time, not much later than you with the 6 hours change. Of course, after a bit I had to take the car back to the airport near here, which took another hour.
I hope you didn't have as much snow as we did.
It was nice to meet you again, we'll see if there will be more MOC Tours for any of us in the future.
PS. I see that they now have snow in Berga, so we were lucky to escape...
