Wellfleet Audubon Sanctuary....a peaceful escape.

We were tourists yesterday!  Yup, we got away from the Fort Hill Bed and Breakfast to take a nice long walk in the Wellfleet Wildlife Sanctuary, an Audubon area on the Bay side encompassing acres of marsh and upland in North Eastham and South Wellfleet.  We came across this shorebird that gave a surprising flash of white when it flew off.  A Willet?  That's what we are thinking....any better ideas?
