I traveled north this weekend. I've always find it interesting how the ice conditions change from one area to another. Down here in Walworth County we have smaller sized lakes that have 9-10 inches of ice as of last night. Larger Lakes like Lake Geneva and Lake Delavan have safe ice in the bays, but there is a lot of open water. Then travel a couple hours north to Castle Rock or Petenwell and you have 20 inches and maybe more.
