I've thought all along I would like a radwagon but am wondering about the radcity instead. Sounds like the wagon is 15# heavier and longer. I'd use it for the grocery store and joy riding. I think I would use these bags for either one. I saw a video wher someone was using them and liked them, they are reasonably priced.
