I'll second Blitz, the ice was pretty slick Wednesday. Probably worth cleats if you're not sure-footed or want to play it safe.
With more folks coming to town, I'd rather support safety in the name of good sport. If you're coming of Noffke's, you'll see tree line to the east but most action is north, north west. Avoid going straight north beyond 1.5 miles, as noted in other posts, that's heading toward the spring, roughly, by Norwegian Bay. Best to go northwest for safer ice, plus the vehicle group will give it away.
I was drilling with a Trophy Strike 8" 120v. I made it through without the extension, but it would have been nice to have. Others who have difficulty bending over may want an extension.
Not participating this year, so good luck to all on the chain this year!
