Where are all the DINKs hiding?

Mid-30s DINK (dual income, no kids) couple here in northern Westchester. We live in a more family-oriented community, but we want to know: where are all the 30s-ish DINKs hiding? What are they doing out in the wild? If they're anything like us, they're at home playing board games or video games, but I want to get out there and find like-minded people that don't have children. We're also over the clubbing / partying scene, although not opposed to a nice drink here and there.
