When I had the house and hut at Big Bay, Point that was a common occurence.Chainsawing a hole was the thing to do.As Brian said,if you move your hut and don't mark it,or some daily guys didn't use augers only chainsaws.I'm glad I didn't take a wrong step.Another catch 22,who pays the rescue,hopefully not I. I think ice will continue to be a grey area as it can be here today,and gone tomorrow ,thick today,thin tomorrow etc. Common sense is all we have.
