From the Enfield listserve:
Is anyone missing an ice shanty? We had one appear in front of our house the other night, so we thought maybe someone moved someone else’s shanty as a prank. The trouble is that it is on thin ice, and very near open water where the brook feeds into the lake. If this is your shanty, I would recommend moving it to safer ground ASAP before it falls into the lake, especially since it is supposed to be so warm over the next few days.
