Well BB, it's not really wise to be alone in the woods! Yes, be alone while on stand or in groundblind, but always try to have a hunting buddy or two in the same area y'all are hunting. Just because your brother-in-law is unethical doesn't mean everyone is!!
One word of Caution, Know your hunting buddies real good! To be Ethical, Safe at all times, Non-Drinker and has Respect For The Law.

I ran hog dogs for over 45yrs with my hunting partner and we understood each other when in the woods.
