You can get a ticket for riding a bike while drunk.
Also, cops are kinda asses about opencontainer, especialy in fron of the bars.
When I went up there the last time, there was a place that claimed the worlds longest bar. Kinda sucked, they had all the taps shut off, so it was mostly cans, and not cheap.
The beer barrel dosent have pitchers, it has buckets of beer. You use a cup to dip in the bucket and fill your own glass. I think you can keep the bucket though, cant remember.
