This is a very informative thread. At large OTS shows, I tend to hang around the gear untill the FOB stops raising his master faders. With a couple of db headroom I flick on the "hold" button and frequently go for a stroll. Sometimes I hand out in another part of the venue with friends, etc. All this is clearly in the situation where there is a roped off section (read no wooks bumping into shit) and plenty of other tapers. I will then wander back to the section every ten minutes or so to check levels, make adjustments, etc.
However, at bars, theaters, or wherever there the TS crew is more fun to hang out with, I'm there.
