Ken,
Thanks for this report, much appreciated.
We had hoped to make it to Foster Pond but ran out of time. After Keiser Pond in Danville, VT,
wonderful as reported, some of us circumnavigated Martins Pond (near Foster Pond as you note), on mostly uniform 2" ice (as tested by ice screw). Thinner plates on part of the northern shore, with visible boundaries and auditory differences if paying close
attention which got harder as flurries fell. Thicker plates closer to the very accessible parking area. More than 1/4" snow when we left late in the day so not sure what to expect for the foreseeable.
