if they were asleep at night you wouldn't be able to go out deer poaching, now would ya? not that thats cool, but you never hear about a deer that ran in front of a car in broad daylight. they hide all day.
deer are on the bottom of the food chain and are paranoid for a reason, its how they survive.
unless they live in a county park and feel real safe. i saw about 8 deer walking around the pond here at my local county park, van saun park,(in Paramus NJ, hustling suburbia, rt 4 and 17 hwy's are a short walk from the park) i was shocked to see them there, then they crossed the park road and blended into the wooded area, cool sight i must say. as long as they dont hit my car or eat my bushes im a live and let live kind a guy.
