I always walk in and out with a BO cap and wear it when in a ground blind but Iusually take it off when up a treeit just makes sense to me. I have hunted in alabama and if I remember correctly a hunter was required to wear a minimum amount of BO(cap) 200 or 250sq inches?while walking to a stand or ground hunting but could remove it when higher than 10 feet off the ground. i would like the NYS law to be similiar to this one.
