Ok, so does anyone else have a problem with their bag being REALLY heavy? I don't take everything with me to shows, just what I need! But nonetheless, I've ended up with broken blood vessels on my shoulders with the past 2 shows I've done. And it's not as simple as buying a rolling cart; I live in an upstairs apartment so every time I have to carry it up and down at least 16 stairs. This last show I had, I had to take my large bar pan, DCB and trifle bowl. I think the bag weighed more than I did!! Any tips or ideas?
