Yeah there is no doubt some deer will be bred around this time. It's not an all or nothing deal but rather a bell curve (good call Daver). Some get bred early, some get bred late, majority get bred around the same time.
I actually have trail photos last year of a lot of all day buck movement on Oct 21. Then on the 22nd I have a pic at 8am of a buck chasing a doe deeper into the timber. Well for hours her fawn hung out in front of the camera and then about 2pm (7 hours later) the doe come back into view and the hair on her back end is all ruffled up...I'd have a hard time believing she wasn't bred that day.
Even knowing that, I'm not rushing to my stand until Tuesday when the cold front rolls in.
