Our chapter is located in southeastern New York State, and covers the counties of Dutchess, Orange, Sullivan, and Ulster, the southern halves of Columbia and Greene, and the southeastern tip of Delaware County. (That is, those sections of Columbia, Delaware, and Greene for which the zip codes start with 124 and 125.)

For you statistics fans, that's roughly five thousand square miles!
