C.D.W. events are easily accessible from New York City.

Take Metro North's Harlem Line from Grand Central to White Plains (about a 30-minute ride).
It's a short cab ride to the church.  (Tell the driver it's the corner of Bryant and Grandview; the entrance itself is on Grandview.)
Or call Susan at (914)762-8619 in advance to find out whether "Bluebell" will be available to pick you up
at the train station in White Plains and drive you to the dance at the Church in the Highlands.
