The deer Density in the area your hunting is def number one in the ingriedients for a succsessful hunt, and number 2 is knowing where, how and when the deer in that area are moving, eating and sleeping.

I hunted a field strip last year where you could literaly take a plastic bag and fill it with deer droppings(very fresh) in no time. I hunted it in the mornings, the afternoons and evenings, no moonlight, full moonlight, pre rut, post rut, rainy days, sunny days, cold days and warm days!...did not see one deer! Conclusion? its obvious! they were completly nocturnal in that area.
