FIshed Carry Bay today. I walked out without any problems, shoreline was tight after the cold weather last week. I'd say 12 - 14 inches of ice in the bay.
A crew of pike fishermen went out before me, they had a 4-wheeler with a trailer to haul all their gear. One guy and a kid on the wheeler and the other 4 -5 walked out. I wouldn't reccomend a 4-wheeler but they seemed to be fine with it.
Stay safe
