After reading the posts regarding the Black Terns earlier today, I drove to
Violette's Lock arriving at 2 PM.  Approx. 20 Black Terns were feeding over
the vegetation just above the the rapids.  Thank you Dave and Mary Ann
pointing me to a life bird!

Also of note was an Olive-sided Flycatcher hawking insects from a tree along
the towpath.
