re: Listening to the games on the radio in the old days

In the early 80's we moved to California and to listen to the games my dad would call my aunt in Lafayette (long distance was ridiculously expensive back then) and she would leave her phone by the radio. We would put the earpiece of our phone next to a microphone attached to our stereo system so we could hear the games. I was just a kid so I have no idea what my dad was paying for the long distance but it had to be high...
