Holy crap, I know we have a lot of ice here but I don't think we'll be needing extensions any time soon!!
I would imagine on the smaller lakes we have over 2 feet now, and probably more by next weekend. I drilled 18-20" 3 weeks ago on a small lake.
Best thing about this thick ice is the lack of people! I fished another small lake last weekend and there wasn't but 10 holes on the whole lake when I got there! Sure am glad I bought a power auger!
