Hmmm, perhaps Axpona 2012 Jacksonville Rich? Had 18s there. If it were Hotlanta, it might have been at Earthshaking music, were there was a DIY GTG. Did drag a rather early, not for sale version there...2011 sounds about right I think. Unless you meant CapFest 2011...bit further north
Yeah, it was probably CAF. Thanks AJ!
