I have an unattached 800 sq ft barn with 3 sections that includes a room in the very rear (my man cave/hunting storage room). Its completely seperate from the main barn and has some hay and I put a few pine branches in it. It has a slanted tin roof with plenty ventilation. I store ALL of my hunting clothes, backpacks, stands, blinds, etc there after washing them in scent shield detergent or baking soda. Im in a rural area, so if it gets any scent at all it copmes from the cow pastures and horse ranches that surround my house. I put them in bed of truck on may to hunt and dress after I get out of truck and start my hunt.
This year Im taking all precautions about my scent, as I feel that getting into my sites where my stands are I will undoubtedly come across a deer or two.
My 2 cents
