According to our local paper, The Mercury, my town wants muni wifi, or at least they're talking about it. The article is a summary of a meeting of some town authorities. If you want to take the time to read it, more power to ya. Be warned, however, it will make you feel like you're at a typical small town government meeting.
If I were a betting man, I wouldn't bet too much money on this ever happening here. Not after reading the article. I'll keep hoping, though.
