First of all, i'm surprised that Teterow got the GP. Its going to take a huge effort to accommodate and transport people to this very sleepy town, infact I have already been told to forget staying anywhere near Teterow as its basically been booked up by BSI / Riders / etc.
I actually hired a car and went to both the big grass track meeting and the U21 WTC meeting in 2014 (they were on over the same period), what I found strange was despite the huge crowds, Teterow itself was dead, the limited bars and resteraunts were almost empty.
The track was flat and overtaking was difficult, spectator facilities (food, drink, etc, were good though)
Gustrow, just half an hour or so up the road is a decent option for digs, there will also be a meeting there on the eve of the GP, and I hear they are putting on transport to the GP (buses).
It will be a GP with a difference, but my gut instinct is, the Germans will put on a good show...and the beer will be cold.
Ticket prices are very reasonable too.
We've decided to go from Brum to Berlin via Munich using Lufthansa, will then hire a car and drive from Berlin and stay a few km's out of Teterow.
