Sometimes I forget that not everyone has been around as long as others.
No NASCAR races were televised flag to flag before '79. Then for years all you had was Daytona 500, one at Talledega, one at Michigan, and maybe a couple more if you were lucky. MRN was your only source to know who won, unless you subscribed to Grand National (now Winston Cup) Scene. Then ESPN got the contract, but cable wasn't as available as it is now. My folks still don't have cable in their area, so dad bought one of them enormous satellite dishes....the big buggars that took the whole front yard.
Some of my fondest memories of childhood are Sunday afternoons, listening to MRN in the yard, maybe washing the car, maybe tossing a baseball with the old man, maybe just stretching out on old quilts in the shade and cutting a watermelon. To this day, I listen to way more racing than I watch.
