The Glorious Insanity of Turbonique
Holy smokes! I didn't believe anyone would have the stones to put a rocket on a kart, but apparently ol' Jack still had a pair of "unmitigated, glorious, throbbing balls" in his eighties :
Unfortunately, Dr. Guest passed away a few years ago as well. I actually heard a bit locally about it at the time because they mentioned his drag racing days. Plus, he was one of 15 or so people who actually lived in Phoenix in the 60s, so that's impressive too.
I realize it's been a few years since this was first published, but whatever became of your rocket supercharger?
