Fished a few hours on 3.5" of rock-solid black ice in Ashfield yesterday. Got a mess of small rainbows and some micro perch on spoons. I'm guessing that the other spots in that area are ready or darn close.
Remember that early ice is dangerous and should always be treated as such. Ashfield has swirling current and while i was on good ice there are still spot there, like many lakes and ponds, that you'll go right through while surrounded by safe ice on all sides. Pics to come, maybe.
