Below freezing temperatures in the daytime and overnights last week were aiding ice formation on area waterways around Door and Kewaunee counties.  That may put anglers in an ice fishing state of mind.  Wisconsin Department of Natural Resources Conservation Warden Chris Kratcha says caution is still needed, especially with holiday temperatures turning milder.

Kratcha urges those who do venture out onto ice-covered waterways to let someone know exactly where you're going and when you'll return.  He added a fully charged cell phone is a must in case you need to call for help.
