They do have a very good sense of smell but poor eyesight. That doesn't mean they can't see! Ask your hosts where to aim on the animal, it's easier than me trying to explain it. Their vitals are farther forward than deer. I have killed dozens with my AR in TX. The laqndowner will tell you everything you need to know about scent control, shot placement, where to set up by the feeder. Have fun!
