You folks with ~60 OTA channels are lucky. Real lucky.
Here in Huntsville, AL where mountains and valleys are the normal landscape, the only way to receive OTA stations from other cities is to have a 100 FT tower, high gain antenna, and live on a mountain top.
We have 6 broadcasters in our city, not counting the religious stations. With DTV subchannels included we get a grand total of *TWELVE* OTA channels. This includes the major networks (CBS, NBC, ABC, Fox, PBS, CW), two PBS subchannels, MeTV, MyNetworkTV, Antenna TV, and Bounce TV. Not really the kind of variety that can replace pay-TV.
My only point to this post was to say that I envy you folks with ~60 OTA channels, that is, if those 60 channels have different programming and aren't duplicates of the same networks.
