The best arguement against it was overheating (and the wheezing sound my lungs would be making scaring off the deer). I have imitated the cadance of a squirrel. Three quick steps on my toes, stop, three steps. Seems to work. I don't always do it but helps when I have to quickly get through an area with lots of dry leaves. I find I'm more successful just being EXTRA SLLLLLLLLLLOOOOOOOOOOWWWW. I make no more noise than a bird rustling in the leaves.
