Not very smart to go hiking alone. Also, someone must know your itinerary. How about checking the weather forecast? What happened to this woman is a perfect example of what could go wrong when one does not follow the basic rules of hiking safely. She is lucky to have survived.
An American woman has been rescued from a German mountain after sending an signal for help using her bra. The woman, who had been missing for more than three days after being hurt while hiking, hooked the brightly coloured sports bra on a cable used for transporting logs to a valley below, hoping it would lead rescuers to her. The 24-year-old outdoors enthusiast from Colorado was hiking alone in the Bavarian Alps near Berchtesgaden, close to the border with Austria, last Monday.
She lost her way when the weather turned bad and she fell 18 feet down a crevasse, injuring her shoulder, ankle and head. Hoping to attract the attention of rescuers, she sent the bra down the valley on the cable and hung out her underwear on a crag. She then waited, with only a small flask of water and some biscuits to sustain her. (Link)
