whats the coldest hunting that you ever did and whats the hottest? details/locations. I was just talking to a friend of mine that just got back from U.P Michigan and they where fishing ( not really hunting ) on a private pond near land O lakes and hunting near calumet. The weather was pretty cold. Upper teens to single digits overnight. They are happy to be back in sunny Fort Pierce Fl where the temps are in the high 70s low 80s.
