I'm on the border between Middle TN and West TN. Chasing has been insane this year (started in late September). Bucks were cranked to 11 over the weekend. Very little sign of actual estrus, but bucks didn't care. We saw multiple chases from the stand Saturday through Wednesday, and a crazy number of chases on camera.
Also noticed around the 5th that does suddenly switched their attention from the overhanging limb at scrapes to the ground scrapes themselves. In the past, this has been a very predictable harbinger of actual estrus in 5 days. So looks like estrus should kick off in mass around the 10th, which is right on schedule for a peak breeding of the 10th to 20th.
