I'm tempted to spend a bit of time there next year. I occasionally do some work for some guys not too far away from Berlin so I have something I can justify it with (northern working class roots means I still think of travel as bourgeois frippery). I'd be interested to see any lists of meetups/that kind of thing that happen regularly.
My dad spent some time there in his army days and I remember him telling me that beer was cheaper than a cup of tea from the roadside stops. Glad to hear that's still the case!
