towing

So when I was in my gmail, I noticed this ad on the right about some gadget that converts two bikes into a tandem. Marketing works since I actually clicked on it and found this website. Basically it's a telescoping towing device. Looks like it's meant for kids but hey why not towing another whole person? If this thing was way cheaper, we would be totally getting one and charles would be working a whole lot harder on his bike...
