I had never heard of the October lull until I started bowhunting. I have had nothing on my trail cam but does for the last 2 1/2 weeks. I occasionally will get a mature buck, but nothing like before. I don't buy into the whole acorn idea, because I constantly have 5-10 does feeding underneath me while hunting. I would guess the big boys are laying low. In my case I think they disappeared off the face of the earth.
