Stealing this from OGF, I too think everyone who goes out onto ice should watch!
I have gone thru ponds and into the bay more times than I care to admit. Most being ankle to waist/shoulder and close to floor and atleast one buddy around. Young and dumb.
As far as what? That was open water yesterday and forecasted temps are in the 50s. I would head to Saginaw Bay or a local pond. I don't see Erie being accessible any time soon.
