As a kid in the mid 80's I met Paul Newman at Watkins Glenn Race Track in New York. He was in the Paddock with his Nissan 300ZX. He apologized for not having much time for us due to prepping the car, but my cousin and I both got our picture taken with him and he was very nice. He was also a very good driver. He finished 2nd that day.
I met Patrick Dempsey at Thunderbolt Raceway in New Jersey about 9 years ago. My buddy and I went to get beers and we saw Dempsey. He looked familiar but we couldn't quite place him as he had shades, jeans, and loafers on. Two girls were excitedly getting their picture taken with him. They left and we walked by Patrick. He stopped, said hi, and I think he was waiting to see if we wanted pictures too. We talked a little then went on to beers. He seemed genuinely nice. We realized who he was when we saw his Mazda RX-8 in the Paddock. Women were going nuts over him as he backed out to get onto the track. I think Paul Newman at age 75 would have kicked his ass around the track. Patrick is a skilled driver but Newman was an excellent one.
I used to regularly see Davey Jones from the Monkeys in Selingsgrove, PA. My buddy's mom was a bartender at a Restaurant and he was there often. He was a pretty hard drinker. He seemed nice and pretty cheery. He also REALLY liked it when people recognized him and made a deal about it. He liked the notoriety.
I met R. Lee Ermey from Full Metal Jacket on a Navy Base here in Maryland. He went to different commands on the base. The other commands got the R rated "drill instructor" version of him. Our highly PC Commanding Officer asked him to tone it down so we got the PG version. Ermey shook hands, smiled, and talked to anyone who walked up to him. The Officers took up most of his time so I didn't get to do much besides say hi, tell him where I'm from, and get well wishes from him. He seems outgoing and pretty cool.
The guy who played Fender in Van Damme's Cyborg was at my Navy Boot Camp Graduation. He was apparently there to see a newphew who was in another recruit division graduate boot camp. I didn't meet him but it was cool seeing him there
