Sounds like a fine plan if you ask me. I don't know how much I'll have to offer, but I can attest that I'm certainly a ravenous superfan who can never seem to get enough.
To answer your question: Hands down 2008-11-07 - Philly @ the TLA. This was, I believe, my fifth Goats outing and my favorite because a) John broke out Attention All Pickpockets, which is my second favorite tMG song (closely behind Gameshows Touch Our Lives), b) a very rare showing of The Boys Are Back in Town cover, c) The Mess Inside, d) Source Decay. All around good energy and one helluva showing.
I think my next favorite would have to be 1997-07-16 - Olympia @ Capitol Theater due to all of the clutch oldies, especially Itzcuintli-Totzli Days, It Froze Me and Orange Ball of Hate.
How about you? What are some of your favorites?
