A NASCAR commercial featuring slot cars prompted a "that's cool" from MAS. What's cool? He gave me the 101 on the art and craft of slot-car racing. This wiki is almost as good as his explanation.
A couple of days later he smiles and says, "here's your debut effect" pointing to this article in the Wall Street Journal that describes the comeback of a hobby in which tiny electric cars race around a plastic track with grooves, or slots, to keep the cars on course. A quick search revealed plenty of blog interest in the hobby such as this one.
Even if these events were fueled only by NASCAR-mania and even if I remain impervious to the charm of all things related to racing automobiles, I'm again pleased by the power of awareness.
