Marcy had kindly picked a hipster café near an S-bahn station that would take me directly to Schönefeld, so I couldn't mess it up. With decor lovingly crafted from crates, and Fleet Foxes on the sound system, I felt very at home.
We talked bikes, Berlin and conventions (furry and Star Trek), and agreed that I should come back in warmer weather and hire a scooter. Then I walked to the station and had a pleasant journey through the winter countryside, spotting a kestrel and a Mitropa dining-car (as seen in the DDR Museum) along the way.
I had time for a gin and tonic in the lounge, followed by coffee and cake, before my flight was called suspiciously early so we could all stand in a queue at the gate for half an hour.
The flight and my journey through Stansted were smooth, though, and I made it home in time for Remington Steele on 5USA.
Verdict: still in love with Berlin. Going back sooner rather than later.
