I just bought a Bell child trailer on craigslist for $40. It has a replacable front wheel which gets me stoked cause I can bike it or I can walk it to the nearest store. It still has the cloth and stuff for kiddos (which I don't have), I'm wondering if you kind folks can give me some ideas to convert it so I can use it to do ALL of our grocery shopping and other similar errands. This is one step closer to convincing my wife that a car isn't necessary so I want to make a super useful trailer. Suggestions on how to convert?
