As yet, no, unfortunately. And to be honest, I wasn't really thinking of using one on the roads, I was just testing the principle of non-wheeled craft on public roads. I'm working on something far more interesting…
As an aside skidartist, the Gander Bender wasn't one of mine, I'll be intrigued to know what one is though!
I have missed a couple of great ideas. You know the large-stack-height crown-race Hope and CK are now making? I invented that a couple of years before either, except mine was better in that it would work with any headset (although different sizes for 1", 1 1/8", 1.5" etc). Never got round to getting a patent though. Also invented a squirrel-proof bird feeder which I have since seen advertised in the inovations catolouge. Bit cross about that too, but also no patent.
I'll not give away the secret of my astronaught training-aids here though, still a work in progress.
