Here we go. I found this on http://www.adventuresofgreg.com/RocketMain.html. This is a beautiful design, although I am not sure how it handles high speed turns. Rear steering is not the best way to turn a vehicle, you tend to lose control too fast. At any rate, this vehicle was built by Greg Kolodziejzyk of the web site listed above for an attempt to cross Canada. It is a lean steer designed delta trike.
