Nine years on one grinder and it just died on you?

Man, the back pain from hauling stuff by hand is no joke. I did the same thing for craft fairs for a while and by the end of setup day I could barely stand up straight. Dropping from 40 minutes to 15 is huge, that's basically an extra hour of your life back every market. The trunk space thing is real though, especially when you gotta fit another person's gear in there too. As for the wagon carts, I've seen people use them at outdoor markets and they seem to struggle on gravel unless the wheels are the big chunky ones. Curbs are hit or miss, you usually end up lifting the whole thing anyway.

My track record with "clean" bags is basically a gnat welcome party.
