This is my big food plot. Deer come from the direction of the red arrows. The green x is where my shooting house was. The blue arrows are the two drainages. The yellow x is the new shooting house location. From the green x the thermals were taking my scent directly to the deer before they ever got in the field. I got busted all the time. Granted, the prevailing wind in the winter is out of the north. But even on a calm day or a slight southern breeze, i would get busted. The yellow x, where my shooting house is now, allows the thermal to take my wind down the ditch its sitting over. This has worked really well for me. Completely changed hunting this field. Also, coming into the field in the morning, before daylight, the wind is almost always in my favor. I rarely ever get busted here
