If you are lost, and want to be found sooner than later, make your fire as smoky as possible.. Smoke can be visible for miles so staying close to your fire and creating plenty of smoke is a good idea. 

Rule of thumb is build shelter out of greener material build fires out of dead stuff. The reasons should be obvious. 

I just had the most interesting conversation with one of my largest distributors. We were discussing sales of one of his biggest selling items, and he made the comment that “People buy it but will probably never need it”... 

I was STUNNED… I was stunned by both the fact this product has uses far beyond an end of the world scenario, but also by the fact he would sell a product he did not feel his customers would ever really need.
