As patriarch of deer camp, I have the responsibility of keeping the log. Years ago, I hit on the idea of entering the data in a spreadsheet, so I would eventually be able to do analysis. This is what happens when a guy with 40 years in computers becomes patriarch.
One of the interesting stats I've found is that despite the rifle season being two weeks long, nearly all of the mature bucks we have taken have been shot on the first two days of season. It's actually even tighter than that. Usually, if you are at our camp, your season is pretty well determined before 10 AM of The Opener. If you don't have your buck on the pole by sundown Sunday, you know you are in for a hard slog.
There are good reasons for this:
1) With just one buck tag to punch, you stop hunting for bucks after you've punched your tag.
2) Hunting is intense in our neighborhood. I've estimated 1 hunter per 20 acres-- Lots of rifles, lots of shots. It is going to be hard for a big buck to go unseen.
3) Our property is thinly hunted and we don't run ATV's around a lot. As a result, the neighbors' deer seem to use us as a sanctuary.
4) The Opener is set to coincide with the peak of the rut. The second Saturday of November dances around from the 8th to the 15th or thereabouts. Some years The Opener is absolute magic. Some years it's a dud; the rut and the weather and Providence decide.
5) Over the years, we have all picked our best spots for The Opener. Everybody has a favorite spot-- partly due to safety and partly due to to superstition. As a result, we normally connect with big bucks when things favor those favorite stands.
6) If you figure that the peak is right around The Opener, then somewhere in the next week is going to be the breeding phase of the rut. Somewhere in there is the dreaded Lockdown Period. Things usually open back up by the next weekend, though. However, the action is considerably more subdued.
