Lake of the Woods had some bad press when some anglers drowned going thru the ice in a hired Bombadier. In my experience they now go out of their way to be safe. Morris Point closed their road access in the middle of our trip a few years ago in mid March due to deteriorating ice. That in spite of the big money that decision cost them. They had a resort full of fisherman who went home early with partial refunds and plenty of bookings to cancel.
I know page one paragraph on of the Minnesota DNR Ice Safety Booklet states the ice is never safe. But if the LotW resorts have roads open I trust their judgement. We go off road so I seldom drive my truck out as the ATV gets around better on unplowed snow.
One other note. If you do not already have a room booked it may already be too late to get one for a Friday and Saturday in December. The late ice will push demand for the last two weeks in Dec. sky high by those forced to cancel their early Dec. trips.
