Like JimPic said its probably his bedding area for getting out of the weather.

Don't be concerned about it being close to a parking lot. Many people pass the area thinking that a buck wouldn't use this area do to being to close to the road or parking area.

My hunting for the last two years have all been about 300 yards in from a main road. One reason is do to a car accident as I couldn't go farther but another reason is because I have been finding a lot of deer and some really nice bucks in this area that is close to the road. Deer know the areas that don't get hunted a lot and make it a safe area because many hunters just pass that area thinking that they have to go a mile in or whatever. You don't have to go that far. I have been seeing some great bucks just 300 yards in and in the evening I see car headlights going by. So don't worry get there early and give it a shot.

Good luck
