Good ice on Winchester early Sunday morning with ~5 groups out at any given time. Got skunked unfortunately on small & large minnows, about 100 yards off the boat launch. Lots of wind and wind flags, to the point where I was just resetting flags at the end without giving tugs. Turns out one of them may have been a bite because when I was packing up, the line was snagged, and after the leader busted off, I reeled in maybe 30 more feet of line than I had put out, so seems like something took it for a ride and got it tangled up. My two takeaways from fishing Winchester in 12-16 degrees plus wind, and 10" of ice, were that a shelter and an auger drill bit are my next buys.
