I print my own maps so if I am hunting alone I usually leave a copy of the map I am using with the area I am hunting in circled. I also take one of the walkie talkies and leave one with the map. Also have a cell phone. I let her know when I should be home. I will call if I am staying longer.

If I am hunting with buddies we have the walkietalkies and cellphones and are generally communicating throughout the day.
