Mississippi River. If I were to listen to a radio station right now, its call sign would begin with “W” and not “K”. The More You Know. 32.480862-89.555295 16 August 2013 by J.P. Fun and Games Dept 3
I had to Google: http://earlyradiohistory.us/kwtrivia.htm
Is it terrible that I was über excited the first time I heard a radio station identify itself with a “K” call sign? That was wicked cool to me, as was the first time I saw an interstate interchange number based on the milepost.
Not terrible at all!
