Gary,
You make some good points, but if I gave the impression that this double red light system of doing things was ever MY IDEA, then I mis-spoke. It is a good idea; I WISH I had thought of it, but I participated in and watched drag racing for at LEAST 35 years using the "old" first red light system before a guy explained the double red light system to me. He had to explain it to me three or four times before I "got it," so ingrained was the "old" system in my so-called brain.
I'd LOVE to take credit for having thought this up, but...
I'M NOT THAT SMART! Obviously...
But, Tthanks for the kind words...
Bill
