There was really no place to hang them up, but I have shared 1! Flyer (and left it there) across the tables I was kind of passing by... even enquired a few people, but overall, it was really hard to pass the message... People were all about beer, and they did not care much about other stuff... Check some photos here for you to understand the big picture.
Anyhow, it was a good initiative, giving that I did not plan much for it. I have also found that using the @good-karma app made a much more interesting impact! People looked several times over my phone while I was recording the beers I drank. I have told and tried to sell the name... but didn't made much difference.
It was, beer beer beer beer! =D
Lol, you need a sober gathering for that, you cannot teach drunk people anything.
