I have a similar setup. I live in San Jose, and with a digital antenna and an amplifier, I get more than 60 channels, with 20+ in flawless HD. The farthest I think is in Napa. A not insubstantial number of them are in Vietnamese, but still. Sometimes it's nice to just turn on the TV and watch whatever's on in the background instead of having to choose something on Netflix or Hulu.
