There is actually an official algorithm for estimating the cross streets given any address within the Manhattan grid. I don't know if it still is, but it used to be published in fine print on bus system maps. It's a little too complicated to memorize, but you could easily keep it on a note card in your wallet and do the calculations in your head or with your phone calculator.
Right. Manhattan grid. That's easy. I'm talking about the grid in Queens. In particular the middle of Queens. It becomes extremely non-grid conforming in a way a calculator rule can't fix.
