Don't over-hunt your area or stands. Soon the deer(bucks) will have you patterned if you put the pressure on too much. All your activity may have pushed them to a more nocturnal stage. Think about it; they don't have to come out in the light at all because their food is there waiting for them. Any pressure will have them changing their pattern to either moving elsewhere or later in the evening, past last light.

I suggest to hunt with the wind and setup further in the woods away from the food source... between where you think they are bedding. You also have to plan your entrance and exit to your stands. The more you keep blowing out or alerting the deer, the less you'll see over time.

Just keep at it and play musical chairs with your stand setups. You could also make some natural material ground blinds too; mix it up a bit.

Good luck,
