I hunted just south of Big Lake (Bordering the Lake on the South / West side) for about 7-8 years when I was in high school, college, and just after. We would never see deer the first 3 weeks of the season. Warm, Wind, tons of cover, and plenty of food in good rain years. Thanksgiving through December was another story. We would see new deer every weekend and more deer as the season continued. I would give it a few weeks and hit it hard towards the end of the season. I shot my biggest deer there the last few weeks of the season every year. Also if you have a water tank we shot quite a few good deer on cold afternoons at noon when they would hit water. Just my take.
