This was tried in the past, with a couple on display. I simply did not have time to promote/organize it, or I think more would have particiapted. If you and/or another member would like to over see this at SCR7, I will see that there is a table and space avaialble. I think it is a neat idea.
Something else that I always thought would be neat at SCR would be if someone set up a electronic (slot car) drag race game.
