I fished the berry sunday, there were snowmobiles, atvs, side by sides on the ice, personally a 4 wheeler would be ideal because there is maybe 3-6" of snow and lots of ice patches with no snow. Ice was 8-10" everywhere i was. There were a few small pressure ridges and a few 2-3" slushy spots but nothing that would get a 4wd wheeler stuck. I did also see a couple trucks make it back to hawes point
Be careful! I went in with an ATV on President’s day in February one year - It was 20 below. There are warm springs at various locations around the lake. The ice was about an inch thick at this location and about 20-inches everywhere else.
If you go, my advice is stay in the deep water & on the well beaten path!
