I've always sort of been intrigued by the research of Charlie Alsheimer / Wayne LaRouche (sp.?). Charlie lives in Steuben Co. NY (Bath area) and possesses a wealth of white-tailed deer knowledge. They have developed hunting tables (based on the "hunter's moon") that are widely published every fall. I've spoken to him on various occasions (at seminars and such). He is a gentleman and basically a real person. Check out his work for good reading.
