Temple of Yellow Cars
A Games tribe
Why yellow cars, and should we count them? You get 5 points for each one you see. Everytime you get out of your own car, your score returns to zero. I have gotten 30 points in an afternoon drive, can you do better?
Secondary rules...any person in your car may shout out the point value by seeing the yellow car before you do. Taxi's and commercial vehicles are prohibited.
There have been cultish off shoots of the original Temple/Game. This also includes various spurious philosophies concerning the sychronicity of seeing the same yellow car more than once a day. Subjects owning yellow cars may not count their own! This tribe will be dedicated to the validation and recording of yellow car scores. Discussion of spurious yellow car philosophies and game rulings.
And to top it off: A shaded Slingshot Yellow SSR looks better than a bright Red Ferrari...........
