Uh, don't hunt in a horse pasture?

I own three horses and hunt a woods adjoining the pasture. The horses have no access to the woods so it works out. As everyone else said, the deer get used to the horses, but from what I've observed, they really don't get too close to them. They will graze some 100 yards away, but will move off once the horses approach. The horses are the curious ones and will always approach the deer first.

With that said, I think you need to find another spot to hunt - sounds like the horses were there first, and really, where are they going to go?
