I would take a (1) bright color bandana big enough to tie aroung thigh, (2) SAK with blade and flat head screw driver, (3) para cord, (4) whistle, (5) flashlight, (6) bic, (7) bottle of water, (8) meds, (9) cellphone, (10) walking stick

I pick these items because they work well togeather for all kinds of improvisation(sp?).

Tell some one when you are going and when you will be back.
