Charles Banta aka 'Kansas' was a "Bikes Not Bombs" guy (you may still see some of those stickers around) who had a shed/carport work area on Waverly somewhere that looked like BICAS. High school students would be there breaking down bikes/sorting bike parts some afternoons and anyone could drop by and find anything you might need for a bike. He got his raw material from bikeshops in exchange for collecting their cardboard bike boxes and taking them to a recycling center. Tucson wasn't doing this yet. He made his trailer totally from recycled material, as he was committed to doing, and the hitch incorporated a piece of leather in the vertical position for flexibility in steering and strength for support across the broad surface. He later went to a laminated rubber floor mat. It attached to the end of a rear rack so you could still use the rack. I enjoyed and used mine all the time and am sad I had to leave it in Hawaii.
