My skill level- low

my take-

1 stay by/in car- If you can move it/push it so it is in sight of a road, do so. Mark the car to signal help
2 attempt to text for help (everybody's got cell phones)
3)fill large cooler with water from cleanest source- let sit overnight to let sediment drop- filter water off top few inches, or boil it. (use coffee peculator
4) work on signal fire. (worst case- use tires to make UGLY BLACK SMOKE
5) sit tight!- not short on water- go back to old 3 minutes air, 3 hours shelter, 3 days water, 3 weeks food....

If you are not found in 3+ weeks in this setup, you will be hurting- maybe hike out at week 2?
