Using Tree Bark For Survival
Survival Cache
A survival cache is something that will hold things you might need in emergency situations. Not in small emergencies, but major ones like a serious catastrophe or a war on our soil. You bury a survival cache somewhere near home so that you can get it when you need it.
First get 4" pvc pipe about 4 feet long
, pvc cap
, pvc female end cap
, and all purpose cement glue(pvc glue). 
Following the directions on the glue put both caps on leaving it unscrewed.
Now you want to fill it with food, medical supplies, knife, flashlight, fire making supplies, and whatever else you think you might need.
Before you fill it and bury it I recommend you line it with a plastic garbage bag for extra protection from wetness.
Screw the cap on and bury it, you never know when you might need it.
Storing food for winter
If something happens more long term its probably a good to store food for the winter. One way to do this is to pickle fruits and vegetables. For starters you might want to just try regular pickles and work your way up to other things. Here is a pickle recipe you could try from ehow .
Things You'll Need:
* Pickling jars
* 6 cups distilled water
* 3 cups white vinegar
* 1/2 cup pickling salt
* Large pot
* Selection of vegetables
* Crushed red pepper (optional)
* Vegetable oil
- Step 1
Use the right jar designated for pickling. Choose a size that meets your needs from 1 oz. to 32 oz. sizes. Make sure you sterilize them before use.
- Step 2
Use the brine as a base for all pickling. Mix 6 cups distilled water, 3 cups white vinegar and 1/2 cup pickling salt in a large pot. Boil gently.
- Step 3
Choose to pickle your favorite vegetables. For an extra kick, add 1/4 teaspoon of crushed red pepper in each jar. Fill each jar with the vegetables you desire and add the boiling brine to the jar. Leave about 1/2 inch at the top and add 1/4 inch vegetable oil, then seal tightly.
- Step 4
Label and date each item. This step can also help remind you if you added any extra ingredients such as a spicy addition.
- Step 5
Store in a cool, dry place and soak at least 2 weeks before opening to allow the food to absorb the flavors. Refrigerate after opening.
