colleen c, I have been kicking around the idea of a hard sided top box for a while now, but haven't actually bought one because I'm sure that it would fit. I might yet get one if I have to start locking my bike up at the bus station instead of taking with me to work.

On a side note, you are a very creative individual. I'm half surprised that you haven't taken a Dremel or some epoxy and mounted a bunch of lights to that thing.
