"The Wanderers" historical fiction? Fiction maybe. Hollywood fiction.
I grew up in Inwood on the north end of Manhattan island not far from Fordham Rd. in the Bronx which was the big shopping street back then featuring Alexanders department store...and across the street was the recruiting booth where i waddled in once and accidentally joined the navy. In elementary school, PS 98, every now and then a rumor would spread that the Fordham Baldies (fictitiously featured in that movie) were going to attack us after school. The kids who went to the nearby Good Shepherd Catholic school told me they were terrorized by the same rumor. The way i heard it the Baldies were a gang of negroes with shaven heads who came up from Harlem, but no one ever set eyes on an actual Baldy. I think there really was a gang by that name in earlier years. Thankfully i never saw one. The guy who would know, a highly intelligent friend of mine, Jim T, knew a lot about those uptown gangs from the rough earlier days, including first hand knowledge because be was a brawler and gang member himself. Sadly he is no longer with us. He passed away about six months ago. He was a real interesting guy, a young inwood lowland plug ugly, he became the mayor of a town in New Mexico and also held various government and private positions in Latin America and i don't even know what else he did. He was a terrific witer. I know that. One of the last times i heard from him he sent me a photo of himself with the boxer Alexis Argello who was a friend of his.
