I still remember the time I found Car Talk (late 80s?): I was driving from Arlington MA to Lexington with the radio on NPR, mindlessly listening to some call-in talk show. A caller was asking why there was blue smoke coming out of his car's tailpipe: The smartass who answered said that was exactly what you would expect from red shift. It was such a high-level quip that it woke me out of my driving trance. "Who are these guys?" Several years later in grad school, I used the Good News Garage (which was about a mile from the MIT campus?) to replace a radiator. It was a little odd to be talking to Ray in person because I had grown used to him being only a voice. Nevertheless, he was a good enough guy.
