Because I run a season-long photo census, I can look at the number of unique bucks on camera for the entire season, month by month, or even half-month periods. Tracking unique buck numbers on half-month periods from August through December (1st to 15th, and 16th to 30th/31st), the normal pattern is for the unique buck numbers to climb all early season and peak the first half of November, then the numbers fall through the rest of the season. However, this year produced a very unusual pattern. The numbers climbed to a peak in the last half of October, then declined the first half of November, only to climb again to a second peak the last half of November. And that second peak in late November is being driven by the surge in buck activity during the period you mentioned, more specifically Nov 27-30.
