I'm on a listserve of other artisans [most of which, like me, do photography] who attend art shows and we discussed having a packing list. I said I'd provide mine, so it's uploaded here: Download MASTER ART SHOW CHECKLIST. I'm sure there are many other items I could take, and some I need not take. And I don't necessarily take everything each time, but this list has developed over the years and I find it helpful when I'm in the 'getting-ready-to-leave' stress mode.
