Pepin ice!
It takes longer to freeze up good! there are areas that do get fish-able ice fairly early but dont venture far until the cold temps set in for a prolonged period of time! even then stay away from points and neck down areas! these areas have faster current and less ice!
remember this is not a lake it is a river! ice can change very quickly! could be good for a day or 2 and then open water! always take caution on pepin!
if you do decide to go check it out and walk out on it take a spud bar and constantly check the thickness of the ice as you go!
be safe!
