In years past the magic date had been Nov. 3 but the heat put a stop to it last year. They kinda did their thing but at night. I was fortunate enough to kill a mature 154" but sightings during the day were slim. I'm looking at the second week of Nov. myself but God will make the final call of weather and if something walks in front of my arrow. Last year He sure did letting the biggest deer on our farm walk past at 38 yards. Our camera pictures went through the roof after I left to go a funeral last year in Dayton on the 6 the with a major change in temp. So Mrbb is right weather probably biggest factor. Good luck.
