I only picked one, but really, all of the above! I seem to have had my best luck a little earlier so I put down Nov 1-5. Does aren't ready yet but the bucks sure are looking around and trolling for ladies. Seems that once the does actually come into heat a buck will hang with them in some secluded corner and they don't move much until he is done with her.
Toward the middle of the month seems like it is more feast or famine for me. It can be incredible, but as often as not early in the month is better.
