My guest today is David M. Sinclair. David was a Marine Surveyor for 60 years, an avid sailor, and still, at the ripe old age of 91, is a nature enthusiast! David is my oldest guest and my beloved uncle, the eldest member of my extended family! I admired the playful, prankster loving relationship he and my mother closely shared. Raised as a Quaker in Germantown, PA, Dave remembers a teacher at Germantown Friends School igniting his love of bird watching.
