I just checked Pymy this morning. North end and the whole lake for that matter is 2 1/2-3" solid black ice. I check Jamestown around the whole pa side to Red Cross. Best I found was manning at 3 1/2-4" at 100yds out, another 100 and it was 3" next 100yds it was down to 2 1/2". The 3 1/2-4" and 3" was checked with the flasher and sitting between 4-6 fow only. Tuttle was sitting right around 3" but only 200yds out. Next weekend is my guess for the start of it all. I'm sure people will push it this weekend, there were people out on it in dec during the first freeze on the Jamestown end.
