I was introduced to Betar by Dennis Lipkin. It's mentioned here. He brought a bunch of us "Great Neckers" to the Manhattan Moadon and then brought Betar to Great Neck.
I hadn't heard of Betar before, even though I was already involved with SSSJ and NCSY.
The 1960's was a magic time, full of idealism, The Man of La Mancha and the Six Days War. I'm not going to say, "to be young, again," since I don't "feel" old. My idealism hasn't tarnished a bit.
