I didn't read all 3 pages of this thread, so can I assume there will be the date change for a similar 2015 event?

as an attendee at a gazillion gunshows and reptile shows and Butler County auto parts shows and computer shows of old here in the Pittsburgh area - I would think such an audio fleamarket show of folks showing up to sell their "spare" audio eqpt - would be a great idea.
