Being in Alaska, it is common to see "survival kits" sold to campers, fisherman, hikers and so on. Two items in these kits are crucial.
One is a deck of cards for playing solitaire. No matter what, shipwrecked, butt frozen to a glacier, mauled by a bear etc, if you need help start playing solitaire and some one WILL be looking over your shoulder telling you "red four on black five". This scenario often leads to a successful rescue.
The second item is panty hose. If the solitaire ploy does not work, you get out the panty hose and put them on. Invariably, three of your old high school pals will show up and see you putting them on. Their laughter will lead the rescuers to you.
Panty hose save lives.
