This is the only info I have on the PLCB. In Harrisburg:
1-800-932-0602 is the Hotline Number in the phone book.
The District Office in Duncansville is: 814-693-6200, but I doubt I'm even going to bother with the local office...and I don't believe they are going to disclose any "facts" and offer assistance in any way.
I know who all of my State Representatives are. They are listed in the phone book (The "Blue Pages".), under Government & Other Public Services. Yours might depend upon your +4 Zip Code, 1 of mine did. They do need to be alerted via phone call, e-mail if one can't do that and eventually, as killjingle mentioned, snail mail.
I'm not only going to mention the unwarranted, rogue "noise violations", but also the asinine law for "underage performers", or their Friday and Saturday night gigs will soon be non-existant. The venues who support them will be fined, as they'll next go after them with a fervor...why not try to tackle it all in one fell swoop? "Under 21s are Musicians too." "What if Shania hadn't been allowed to sing?"

(I believe she is from Canada, but still...) ...or something like that.
If the powers that be haven't done anything to curb the rogue citations by then, when Spring has finally sprung, in addition to all else that is being done - as long as it was legal, mind you, a good old fashioned Peaceful picket protest (Some could carry signs with a Tombstone drawn on them, the name of a place that is no longer in business due to the bogus violations, "R.I.P." on it.), possibly right out in front of either a recently targeted but still open establishment, or :egad: the Hollidaysburg Barracks, even the Capitol in Harrisburg, would definitely garner attention to what they've been doing.
JP, I had no idea about what had happeded at the Wing-Off years ago. I feel that shows someone is either going power mad or they are simply insane.
For laws to be amended, hopefully it's not too late for the Ballot in November.
