i was there 2 years ago.
i was amazed at how many of the girls really did wear the costumes. most of them were riding around on bikes. place was PACKED of course, half meter long bratwursts.
polizei everywhere,but they were cool. as long as you weren’t causing problems, you were good.
oh, how i wish i was there now!
I lived in Germany next to Munich for two years about twenty five years back. It was a blast.
