Some states don't allow you to have two way radios while hunting. I always tell someone where I will be hunting, and that I will call him/her no later than a certain time. If they have not heard from me by that time, they will either come looking for me or contact the local sheriff's office. Either way, someone will be there. The big trick when I first started this system was to remember to call by the time I indicated. The first time three county deputies showed up while I was gutting my deer they ribbed me enough thatI have never forgotten to call again.
