I checked on a couple of ponds this weekend.
Heard Pond in Wayland is only reachable with a LONG plank.
Unfortunately the recent rains and warm temps have eroded the shoreline pretty badly.
The Sudbury River, which feed the pond, is pretty flooded and as a result the pond is high.
That means the shore ice is rotted out for a good 5-8' before you might find good ice.
Many of the waters in and around the 128 belt will probably have similar results, but more remote waters might be doable.
Of course that doesn't take into consideration this weeks weather.....
