I find that with aging that I often have a pile of noise “fall outta me” wether i want it to or not. Sometimes it will startle me as I’m dozing off in the stand. One day it’s a ripping ot tearing sound kinda like a sun-rotted lumber tarp being ripped in half, then other times it’s a qwacking sound like a hen mallard feeding chuckle. Always amazes me how it can change up. Not sure what the deer think of it…..
