Yaphank NY at one time had an Adolph Hitler Drive over in Camp Siegfried. It no longer exists. ................ ?????? What is it now? It was on the Carmen River, canoe territory when I lived nearby. Knowing L.I., there are probably condos there now. Legend has it the streets were named for the Hitler gang. It wasn’t too far from Yip Yip Yaphank, made famous by Pvt Irving Berlin who hated to get up in the morning.
The German American Bund in the mid 30s to just about until December 7, 1941 had a camp there. They were pro Nazi. This was a combination summer camp for Americans of German descent and also personal year long homes. Pvt. Irving Berlin was not welcome
