I think it would be very interesting, really. I would think they would keep to themselves pretty much. None would really know their names even if they took large lecture courses and such... You’d think someone would remember a kid that LOOKED like him...
Frankly, I’ve always thought those pictures of him supposedly during that time looked like he had a “Cuban Accent” to his clothing and style... Who knows. As someone else mentioned, it could be made up out of whole cloth for all we know. Maybe he was in Cuba, and Fidel sent him to NY, and then on to Chicago with Bill Ayers as well, Fidel’s other “friend” here in the US.
