Classical Music Manifesto?

I forgot to share this story when I first heard about it, but hopefully it will still seem kinda interesting. My dad's radio station got a letter from the Unabomber a month or so again. The actual guy, and I'm really not kidding. He's in prison around Florence, CO in a SuperMax facility, within the broadcast area of the radio station, and he wrote a letter requesting that a certain song be played at a specific date and time. Naturally I assumed that he only gets to listen to the radio for a limited amount of time during his 23 hours a day of solitary confinement, but somehow the first thought that occurred to my dad was that he was trying to send out some sort of coded message. Apparently my dad's boss, who is a crazy over reactor, gave the letter to the FBI, because clearly the guy can magically send a letter no one is aware of out from one of the highest security prisons in the country. Probably should have just put it up for sale on ebay.
