OK, so at the risk of losing my ETS membership card

I have to ask a few, perhaps dumb, questions:
- I love pine nuts (from the store). Are these found on the pine cone? If so, how does one "open" the cone and get them?
- Pine needle tea? What, just boil some water and toss in some needles (I assume green)? Any set ratio (ie, 20 needles per ounce)?
- Blast, you mention the inner bark of several trees. After 6 years living outside of California, I can now identify a birch tree. So, by the inner bark, you mean all the stuff inside the outer layer?
Yeah, I've pretty well neglected plants in survival thinking. I probably should go outside and play with the cattails that grow everywhere around here.
