Thanks all. Lots of good ideas although the cork or stopper one seems to be the best fusion of elegance and convenience. The beater was not originally intended as such, right now its just the least expensive bike that works. It is also my favorite ride. Eventually I would like to get one bike that incorporates my preferred features (as soon as a figure out what they are). I'm not quite there yet but I do know that the ability to add fenders is one of the desired features.
