I spend a majority of my time hunting and fishing by myself. One thing I began doing years ago was keeping a small survival kit with me. You can build your own or buy one already prepared. I have never had to use anything but a few first aid supplies, but it is nice to know if I get lost or break a leg or something, I might be able to buy sometime until I can get back to civilization.

I also tell my wife where I will be and when I can expect to be home. It may seem silly and will most likely be unnecessary, but it sure doesn't hurt anything to be prepared in the event of some incident.
