My great grandad says the same thing. He told me about mowing the lawn with a push mower with this battery portable radio hanging off the handle listening the the games.
It’s a very peaceful, calming thing to listen to, even if you’re not really into baseball.
I remember once being very ill with a Summer ‘flu, and hearing the baseball game on the radio lulled me into painless sleep.
Maybe the ASMR folks have discovered this...
We buried my Dad in 1995 with his old beat up transistor radio, he loved sitting in the back yard listening to the games. Brother insisted on taking the batteries out so they would not leak. I advocated for putting in fresh batteries and turning it on so we could hear it as he was lowered down. I lost.
