There is nothing like civic participation. In this episode, we see all four ladies rally together to save an old Oak tree on Richmond Street. While their petitioning tactics vary (and are sometimes questionable), it is admirable to see how seriously they take environmental and historical conservation.   The girls have a formidable opponent in Freida Claxton, a crotchety peeping tom of a neighbor who insists the county get rid of the tree, and when Freida pushes Rose to pfar, she is forced to take matters into her own hands.
