i do not leave my bedroom w/o my pocketknife. i have learned that where i live if i don't have it i will need it. poncho was almost a tie with a firestarter poncho= shelter, dry, signal, groundcover, water gatherer/carryer, it is basically a must have. and i can yell loudly, but for how long? whistles can be heard for a couple miles, and don't go hoarse.
