Mulies have great eye sight and an unbelieveable sense of smell not to mention those dang ears. Best advice I can give is to slow down. When glassing pick apart the shadows. I always found it easiest to find a buck feeding in the morning follow him till he beds durring the middle of the day,get the wind in your favor and make a very slow calculated stalk. I have found that most boot soles are very hard and noisy so I carry a pair of felt covers for my boots, I think they are made by carlton calls. Like I said the best advice I can give is to go slow, cant even tell you how many times I've blown a stalk by getting in a hurry.

Hope this helps
