After season ended this year I was thinking of ways to increase the probability of a encounter with a mature buck other than just taking off 3 months in the fall to hunt so I looked at 5 years worth of mature buck pictures that I have saved. Two things jumped out at me very quickly, #1 starting around October 25th I see a surge in mature buck movement for about a week and most of my cameras are hung over traditional scrape locations at this time even if they haven't been worked since the year before. #2 I will see another surge in mature buck pictures around December 10th for about a week to 10 days and normally these will be cruising through food plots or along travel corridors. not a scientific study by any means but it helped me schedule my limited number of vacation days that I can devote to hunting for the upcoming season. What area of the state are you in, I am as far east as you can go along the NC boarder.
