My parents moved from Brooklyn to the Nassau County suburbs in 1949.
In 1968, they no longer had a need for a house with three children, and a lawn to take care of. They sold the house and moved to the upper-eastside.
I'm going to keep my house. No way I'd move into Manhattan.

Same with us. There is NO way we are moving to any city. We bought a home in Idaho a couple years ago. We actually doubled our lawn area, went up to two stories from one, and moved to snow country from California. We are nuts.
