Went to the winter event, had a blast. For anyone fairly local to Pittsburgh, I highly recommend it.

July 17 & 18
Had a great time here, no silent disco this year though
Just got an email about the Winter Beerfest for 2016. They are selling early admission tickets for the same price as regular admission until Christmas or until they run out of tickets. I just bought mine for Saturday February 27.
