Support system: Networking in the suburbs

Westchester County, which lies directly north of New York City, is well known for its many classic suburban communities where cars line up at train stations at 6 p.m. each day to pick up returning executives and money managers. Through the first half of this decade, it was difficult to find homes for less than $1 million in such Westchester towns as Rye, Larchmont, Scarsdale, Chappaqua and Bedford.
