Really appreciate your input to this thread as I try to redo the Bull Pen approach. You are so right about the differences of terrain and environment across the country, but amazing at everyone's willingness to contribute (always with those disclaimers "now this may not work in your area").
The Bull Pen area has water, normally has some great sawtooth acorns early October, and then some pretty good food plots. What's missing? Very likely it is the feeling of security to walk out into those plots. As I think thru this I am more convinced that I will have two shooting houses positioned at easy access from the road, and keep folks out of the center of the property. The Bull Pen is surrounded by beautiful hardwood hills and bottoms. The deer have plenty to check out during the daylight hours and venture into bull pen only at dark. We've got to give them some safety feeling, and that may take awhile, as even in the summertime most pictures are at night.
I looked again at your picture, of the large active plot that you drive by to other stands. Are most of the surrounding woods pine? I know you have some hardwood areas and beaver bottoms, but looks like pine closest to that plot.
