Been in Germany for two weeks and visited this meet. Massive site, every wednesday with 1500+ bikes every week (weather permitting)
Only saw one copper and no retards trying to stunt/fight/usual nonsense
Have catering units there too, selling alcohol free beer, burgers, coffee, etc
Highly recommend if you’re nearby sometime.
