Just finished a project. Bag Boy folding golf cart, light and very well made, from Goodwill, carrying a very large High Sierra duffle bag strapped on tight. Handle is strapped to the back of my rack. Cart cost $7, duffle cost $6, and I just brought home about 40 pounds of groceries without incident. It looks quite slick, trails nicely at speed, holds a ton, and folds up in a few seconds to the size of a flat duffle. Picks up as soon as I am on a computer.
