Humans walk with the intent of going somewhere. Our steps are faster and more deliberate then anything else in the woods. Cattle, armadillos, and everything else just kind of mosey allong, not in any particular hurry. They don't seem to follow any particular path. I try to do the same thing when I am approaching my setup. I shuffle my feet, probably like 1dahunter, trying to mimic what a cow would sound like. Deer hear them all the time, so they don't get concerned.
