Y'know I might if I didn't live in the Village and have to do the check thing on drinks offered. NY Water is actually better than most metros. It's not a gigantic rock. Next you'll explain how the Statue of Liberty is on an island. And then I'll explain it's on an island of garbage and isn't even in New York.
Fuck dude, you made me choke on my drink.
