which I cant honestly ever seeing myself doing. Ive always taken my barbag with me, as my "this, that and whatever" valuables are stuck here and there and so wouldnt ever take the time to take it all out, plus I wouldnt have anywhere to put the stuff anyway.
I would not like leaving it there empty anyway, in case someone interested in thievery would probably try to get it off anyway, and most likely damage it. Plus I figure I would lose the darn key too, so it stays at home, never been used in fact.

a barbags advantage is having wallet, passport, camera etc all in one easy place to take into stores, leaving dirty underwear and such in the panniers, usually not a target for someone if in a store for a short time. I have used the "leave dirty looking clothes" bungied to the rear bags or whatever for the "ewww" factor of deterrence.
