I don't know that this is the case or not, but I believe it still bares worth saying.

If a doe came out and looked youeye to eye, then you are probably moiving and giving yourself away. You might not even realize you are doing it, but I have found that being busted that hard..... I gave myself up. She might have seen you before you saw her. Check how much you move while in the stand, and when you move, move slowly. Quick movement in the animal world spells PREDATOR. And quick motions attract attention.

Other than that, as previously said. If you can hunt higher, go higher.

Good luck
