Reverse Trikes

I've seen a couple of these Spyder 3–wheeled trikes on the road over the past few months. One was just pulling out of a farm that's right on 163 between Des Moines and Pella, or thereabouts. I didn't know they were made by Can–Am, or that Can–Am even existed any more. I remember they at least made kick–ass motocross motorcycles back in the '70s.
