Harry Carey.
When I was a kid, long before Colorado had MLB, I would lay on the floor listening to the radio as Harry broadcast Cardinal games on KMOX.
I could also pick up LA games, and sometimes Texas and Minnesota.
I've been a Yankees fan since about 1948. My father before me. And, all three of our kids like the Pinstrips. Was in Yankee Stadium last summer to watch a game in the "old" ballpark. Would like to go back to NYC this summer and be in the stands for a game in the new Yankee Stadium, but funds are pretty thin right now.
While in NYC last summer we also saw a Mets game in Shea Stadium. That ballpark also is gone.
The oldest ballpark I've watched MLB in was Municipal Stadium in Kansas City. Yankees vs. KC in 1961 and 1962.
