I have hunted the same base. There are 3 keys to success.

1) Find the food source. If you find what they are eating and when you will be ahead of the game

2) Find the thickest, nastiest cover that you can. For the deer to get big they have to get old. They need a place to hide. If it is thick, most hunters will not take the time or energy to go there. Also I try and find these areas that are as far away from roads or walking paths. Try to find thick areas that are near food sources. (White Oaks are key at the Marine base)

3) When you find a spot, keep your mouth zipped. It takes time to find the great spots and it takes time to find the perfect tree in these spots.

Good luck this year.
