I am not biologist...but I am betting the rut starts the day AFTER gun season is over......it was 75 degrees here yesterday ....said it was gonna hit 33 last night...made it to 41......today 70...tomorrow 75......seems the deer bed down most of the day.....the sky is clear the moon is bright....almost everything is happening while we sleep.....Missouri needs to extend the modern gun season......just like ducks....by the time they get here....the season is over.....
