Carl then recounts, "When I was 13 years old I had some close friends in a Zionist youth group called Betar. They wore uniforms and kept talking about a Jewish state on both sides of the Jordan. I didn't care about that. I just wanted to be with Shloime and Moishe."
P.S. Okay, who was his madrich?
Both Marty Marden and Seymore Rosenberg, z'l, knew Carl Reiner when he was in Betar in the Bronx ken. They often talked about him. I think he must have been older than 13, which would have been 1933 if he is now 86. I would guess that it was later in the 1930's.
