A mild February has lead to weak ice conditions in many parts of Wisconsin, 7.5 degrees above average. Ice thickness isn't as thick as some winters and with March less than a week away it is almost time to get the shelters(or whatever you call them) off the ice.
There is still time to get out on the ice, but remember no ice is 100% safe. Good luck!
Here is a helpful guide from the Wisconsin DNR
