The SF Bay Area was probably full of BBSes, as was the Los Angeles Area, but we had Inter-LATA or 'Zone 3' calling for stuff where the central office was I think more than 15 miles away, but under some limit. Closer rate centera than that was local, farther would go through your long distance carrier. Unlimited local calling was available at a reasonable price, but Zone3 was still charged per minute (could cost more than some long distance carriers)
