I noticed these folks fishing outside my office window today in McHenry Cove. From what I understand, the lake is definitely safe for ice-fishing now after almost 3 weeks of sub freezing temperatures. You can see the community of Ski Harbor in the background, and the approximate location of where the ice starts and land stops.
I have a 2 bedroom condo available for sale at Ski Harbor, a lakefront townhouse community with an indoor swimming pool, tennis courts and beach volleyball court. You can find some more info about the community here.
