Not sure when my yellow #2 Metolius UL TCU disappeared from my rack, as our group of three was sharing a rack. I didn't notice until we got back to the parking lot!
We were just east of the Uberfall: Sixish, Ribs, and Easy O. Thanks!
(And: sorry if this is the wrong forum/venue. I've only just started climbing at the Gunks last year, and this is my first time on the forum.)
