Had a big whitetail come in at a trot, nose to the ground when I was using doe estrus. I was in a climbing stand way up high. I made little rockets of toilet paper, dipped it in the doe pee, and tossed them on the ground around my stand. The buck came in right at dusk crosswind and stopped in his tracks when he got down wind. I thought he winded me until he came right in almost under my stand. He is now in my living room.
Age and knowledge don't always come together. Sometimes you just get the age.
