The Savoy State Forest ponds (Bog, Burnetts, North) should be fine.
I was out on Burnett's on Wednesday, and there was over a foot of ice.
Even with the warm weather/rain we've had since, I am confident the ice should have held up in Savoy.
However, I question the safety of the ice on other northern Berkshire ponds (e.g., Cheshire, Fish Pond) at this stage.
I was on Fish Pond on Wednesday, and it was down to 2 to 4 inches. With the warmth/rain we've had since then, I doubt the ice has held up.
