Regarding the Dec. 26 letters “How best to deal with the deer” and the Dec. 21 Metro article “Fairfax City plans to surgically sterilize deer”:

A question has been bubbling about in my mind for more than a week: Are female deer running around impregnating one another or themselves? Wouldn’t it be more cost-effective for Fairfax City officials to capture and castrate some of the stags than to focus on the does?
