The reason why I'm making a big deal out of the fact that he's not on Public Radio is because commercial radio stations usually don't cover such obscure topics as language. His show is on just once a week for an hour, but still--if I were to suggest a similar show where I work, they'd laugh and remind me that people aren't interested in such subjects.
I looked at the station's site, and I couldn't find his show, but there were some other things I noticed: the station is owned by a shockingly small company, not a huge media corporation (which is extremely rare in today's radio world), and the station has mostly syndicated programming, which isn't surprising, because most radio is syndicated now. So it makes the presence of a language show even more amazing!
I told him what I thought, and he ended his friendly email with these positive words:
Since retirement in 1994, I have had an unbelievable life. Way leads unto way, but this has been one heckuva ride.
