Larry,
Life is full of contradictions, and new knowledge often necessitates that we
contradict our own previous position. But, in this case, there is less confusion
than what is apparent: Yes, we do have two James Nazarian's on the list, and
between us 3 MGA's, 4 B's, and 4 GT's. James, Jr. is attending Colorado
University, and I, James, Sr., regret that I am not. He answers to "James", and
I
to "Jim".
