You have 80 acres, how is this property set up i.e. what percentage Harwood, softwood, field, swamp etc... How does this compair to the abutting properties? Where do the deer typically bed and how far from the bedding areas are you setting up? With the warmth this year are they heading to water prior to feeding? What is the primary food source.
I take it you have your cameras at the food source, what route will they take between the bedding area and the food source? Can set up and intercept them. I would believe the deer are still moving though maybe later but still in shooting light.
You do not have an easy question, many variables....
