The city of Sacramento is trying to get its long-promised wi-fi network moving forward again. Before you call your service provider to cancel your high-speed connection, read the fine print. “Free” means free with banner ads. To get ad-free service you’d have to upgrade to pay about $20, which is a good deal if it all works out. Last time the city pulled out at the last minute after they realized other cities were getting a better deal. Most cafes in the area offer free wi-fi already, but I’m sure there will be even more locations where people will be happy to log on. Parks? Rooftops? Light rail?
