Renfield, calm down. I'm not picking on you. I make mistakes every day. I was just trying to understand you.
Technically, East and West of Manhattan are split by 5th Avenue, at least that's where the streets split East/West. But, for Upper East/West, the park suffices.
You are surely at a prestigious synagogue. That's the original congregation of NY! They've been here for at least 350 years. And, Sephardics, too.
Nice.
