The Oregon Brewers Festival was interesting. I attended with out at OSCON 2007. Lots of tents. Lots of beer. Lots of people.
But the most odd thing of all was the 'beer growl'. Seriously, people would just kinda do this. It was like a roaring growl. I hear this unique "thing to do when drinking good bear" was invented in Portland and is a common thing at this festival.
On my trip out there I had a number of local beers. I don't recall finding a single one I didn't like. I should have kept the labels, because I now remember none of their names
