In Denver, we have the semi-annual parking-lot gear-swap at Wilderness Exchange , my favorite outdoor store a block from the REI flagship store. Two years ago, a guy had a pile -- a virtual mountain -- of very-lightly-used Big Agnes 0-degree down bags for $100 ea. I bought one and have been regretting not getting a second one ever since. Next one's in May.

We've got a Savers in Littleton that has become my great new favorite. I can't go there and not find something, so I limit my visits.

That was a great score on that Mountainsmith Ghost, grit.
