here in newaygo MI we have layered ice like ive never seen it .... 2 inches ice on top, then 6 inches of slush( which you can just press the auger thru without turning ), then 8 of ice that cuts way too easy (soft)....so we pulled the large shack to shore on saturday till it gets more solid or worse......the small shack on another lake I left hoping for best ( I will not need help moving that one if ice takes a turn for the worst real fast).....
