RE: Could they find you??
One thing we teach in Hunter's Ed is to always give a hunting trip plan to someone you can trust to come looking for you.
Give the location and expected time you will return and let them know what to do if you are not back by X time.
Also we recommend carrying a cellphone and survival bag on all trips as well as showing someone the area you will be hunting before the trip if possible.
That being said my wife knows where all my stands are except for 2 and my close friends know where they are at. I tell her where I'm hunting each time I leave the house and about what time I'll be back. If I've taken a deer or am held up for another reason I give her a call.
