PLN was a great, dedicated racer. For years, he only acted to support his racing. We used to see him at the SCCA run-offs at Road Atlanta back in the late '70's. He just wanted to hang out with everyone and drink Buds. A couple years back, Adam Carrola, the comedian, purchased his Porsche 935 at auction for something like $4 million and, to his credit, vintage races it!

Sadly, just like the cars, when I had the opportunity, I couldn't afford them. As a lowly Ensign at Clark AFB, the PX had a brand-new ROLEX Submariner for $167 which was a little over 2 weeks pay so I passed. If in excellent condition today, that watch would be worth around $8,000! I owned a President a few years back but have small wrists so it looked way too big on me. I sold it and bought a smaller face Oyster Perpetual Day-Date two-tone. My "work-on-the-cars" watch is a $25 Smith & Wesson that keeps excellent time.
