Have any of you noticed that deer seem to "bust" us more due to winding us in the latter part of the season than the earlier part? That sure is what it seems to me. Many factors may cause this including:

The pressure of being hunted during the season whereas in the earlier part of the season deer may tolerate human scent more due to farmers and their machinery being in the fields.

Perhaps the air is heavier in the colder weather so scent doesn't travel as far away or disburse.

Less windy days. Seems like its windier overall in the early half of the season than later on, therefore human scent is still concentrated making it easier to scent us.

Maybe I or we are not practicing scent control later on because of being tired, in a hurry, etc. but I don't believe that to be so in my case.

Or maybe I am just full of it. But I get winded more in the later half of the season than the first half. I am speaking strictly of being winded, not seen or heard.
