pick up scrap from a bike

Good on yah for doing what you do, a couple of thoughts though which I think are worth mentioning. In fort worth a bike might be handy most of the time, for many of us in colder and wetter climates there will be many many days where it would not be so ideal. Most importantly your cart might be able to handle a 600lb load but what can the little brakes on your bike safely bring to a hault? I mountain bike a fair bit and I honestly can't even imagine how difficult it would be to safely come to a controlled stop in any kind of a hurry if I had a whole bunch of extra weight behind me and if going downhill.... could get dicey very quickly.
