You never know......

I went out for a walk with no destination in mind, and, about a mile from home, decided to turn down this road and go see the Spencer-Peirce-Little farm, which has been there for 322 years (!)

Then I followed a trail beyond the farmhouse,

which led to the back edge of the Plum Island airport.

I walk on the road that runs by the other side of this little air strip all the time, watching small planes take off and land, but I never knew they called  that structure an AERODROME.
