Field Notes
The patch of scrub weeds and bushes was under three large maple trees. The leaves of the maple trees were very serrated and did not look like sugar maple nor Norway maples. The area was not mowed over for at least a year and probably not for many years. The area was next to cut grass on one side and the Penobscot River on the other side. The area surrounding was developed with roads, a bridge and buildings, even a swimming pool. People probably walked by the area daily.

Thanks for reporting your "not found" sighting! You made a solid case to back up your claim. Nicely done!

And it looks like it was a lovely day for wandering around down by the Penobscot River.

cheers,
