Another really nice guy is Chip Foose.
A friend of mine came to the U.S. a couple of years ago with a couple of other Aussies. I'd read in the paper that Foose's shop in SoCal offered tours once a week so we arranged the time to go. We stopped for lunch at a local spot and Chip was there with someone from his shop. We didn't bother them during lunch.
After lunch we drove to his shop and discovered from the sign on the gate that we'd missed the tour - the tour time was while Chip was out to lunch.
Chip was just leaving again and, as the gate opened so he could drive out, he stopped and said, "Hi", as the gates were opening.
I explained about the guys with me being from Australia and he immediately got out of his car, invited us in and gave us a personal tour of his shop - complete with a demonstration of working with the English Wheel.
