I think with age comes the wisdom of expediency, and for a wildlife photographer, what can be more expedient than photographing the life that lives in your own back yard? My back yard for more than 50 yrs. has been "The Barnegat Bay Estuary". Though different in species and life cycles, all are connected by the food chain that gives them life, either as predator or prey. And though often difficult to photograph, I've never run out of subjects, or felt the need to shoot anyplace else.
