The most important card in your wallet.
I have enough experience to know things can change out here in the blink of an eye.
When your cell phone doesn't work, knowing someone knows where I am at is a big relief.
If I don't make it back by the time expected an email goes out to my family. There is a lot of water
our here, that is why I spend a few seconds to enter where I am going; it can save my life.
