Great question, Steve.
Like most who have posted here already, there are many to choose from.
But, I will narrow it down to 3 guys, which I have been fortunate to have a conversation with for at least an hour (or more) on each occasion.
First......
I met Ted in Cooperstown back in the 1980's, and we talked BASEBALL, Yankees vs Boston (1940's - 1950's), and BB cards for about an hour.
2nd......April 1984, I was on a 1st class flight from Newark to Chicago sitting with Phil. We had a great time "Talkin' Baseball" for 2 hours, plus
our old neighborhood (Phil lived 2 blocks from my home in Hillside, NJ when I was a youngster)
3rd......I met Don in Cooperstown in the early 1990's. A very friendly guy to talk with. And, of course we spent a lot of time reminiscing about
his Perfect Game in the 1956 World Series.
