Hey there SEMO,,, up here in north central MO the bucks are starting to take interest in the does. No breeding yet, but some chasing. I walked through my 50+ acres of woods on Saturday afternoon and found zero rubs and zero scrapes. I couldn't believe it. SO, this year, it's going to be a challenge... I'm going to have to try different tactics and different strategies.
How's the weather down there? Up here it's finally starting to cool off. Today (Tues) it's dreary out with temps in the low 50's. Supposed to be cold every night this week with possible frost every night. I'm waiting for it to get cold out so that I can start hunting during the mornings too. I'm not a believer of hunting when it's warm in the morning. The deer don't seek out that warm sun as much.
To answer your question... here in MO the rut can start as early as the first week of November all the way through the 20th or so of November. Of course, our rifle season is set up to hit the rut during prime time... our firearm season here in MO is November 12-22.
Good luck to you man!
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
