I was wondering that too. I was hunting last night and when I came out there were four deer stand by my truck. Eventually they spooke and ran across the road to a small patch of timber. Will they now know to associate the truck being there with me hunting them? I know in other spots I've hunted we parked a half mile away instead of in the lane that ends 50 yards from a stand we have. By doing that my buddy saw a monster out of that stand and together we saw more deer that day than we ever have before including 3 wall hangers. I think they've figured out that if a vehicle come down that lane then there will be someone in there after them.
