 | | rtl21 - Can Stacking
|
|
Hey folks, I had an idea for a new game, and I want to float it here--see if there's any interest. Previously, I had suggested a "can weighing" game. Whoever ends up with the heaviest can wins. This, in retrospect, isn't that interesting. My new (...) (19 years ago, 2-Mar-06, to lugnet.org.ca.rtltoronto)
