This came from Steve and Bev Allen this morning, sent to me and to Tom Dente:

Tom & Jane,

This small yellow plane landed on the Pond yesterday morning. Bev took this picture - the pilot is standing on the pontoon, and we observed him pumping a liquid from the pontoon into the Pond. Obviously, the plane could have come from anywhere, including water with invasive species. We did not get the registration number, but it began with the letters "AC". He then restarted the plane manually by spinning the propeller, taxied north behind the islands and took off heading south east. We wonder if anyone else saw this plane? Steve & Bev
