I still wouldn't drive a car/truck, thickness is sporadic on S.Mn lakes.
I was on Mazaska 2 Sat. ago and found 9 in the bay and 2 on the north side.
But most lakes closer to Mankato are majority 9ish inches thick, but you will still find 4 and 6.
Also download the app Ice Report https://play.google.com/store/apps/details?id=com.icereportsoftware.icereport .
No snow here yet, bring cleats.
Please download and use the Ice Report app. It is very helpful for all of us, especially this time of year. Reports have been coming in the past couple of days.
