Really interesting story. I wonder if I myself might have gotten into trouble were it not for the fact that I couldn't make that many phone calls. I seem to recall that there was no such thing as unlimited calling - even for local numbers. Not to mention I wasn't allowed to hog our one phone line. Calling a long-distance number for 30 minutes probably would have resulted in at least a $10 phone bill - which was totally out of the question.
I was resigned to call one local BBS and do a direct 1-to-1 modem connection with my only other friend who had a modem!
