I have witnessed the same things on the state land i hunt DeerCamp. The first year i hunted that state land the section i was in was just clear cut (5-6 years ago) i saw a few deer on opening day and other than that it was hit or miss (mainly miss lol!) About 3 years ago i started to notice the cover and re-growth that had happened, and it is amazing! It is extremely thick in this section and their are rubs, scrapes, trails, you name it, (deer sign wise) is is in this section, but like i said it is EXTREMELY thick and is hard to hunt without making major disturbances to get to a stand. But the deer do love it, and im willing to bet this is an area where bucks love to hang out/escape pressure when pressure starts to peak.
Ill def be up there for gun season again this year and i might try to set up a stand on the outside of the thick stuff right before it on a trail this year and hope to catch a buck trying to sneak away from the pressure come gun season. Like everyone has said, the next few years might be more slow action-wise than in the past, but come 3 years from now it will prob be a deer's paradise! Good luck!
Them Darned ol' deer.
