South Texas winters often mean having a 30-35 degree difference between the morning commute and the return trip in the evening. I decided I needed some more carrying capacity then the trunk bag I've been using for ferrying the clothes back and forth. I also use the bike to transport documents during the workday. So I decided to build a tailbox out of coroplast. I originally thought I would use some of the political signs I have harvested after the election, but I thought it would be better to use a solid color that would add to my daytime visibility. Fortunately, I have a plastic dealer in my neighborhood and he sold me a half sheet for $7.00. Add a few zip ties and pop-rivets, and you got some serious carrying capacity for a good price.
