[Thanks to tOP. There's another guy who has strong interest in many things.]
I admire people who have strong enough interest to have an impact in more than one area. Take Jay Leno, TV star, comedian, and car nut. Here he talks about an amazing Bugatti 37A racer. He actually drives it too, from around nine minutes into the video. Like Mike says in his post about roadsters, hardly anybody ever talks about driving these things.
