If it is a matter of life and death for me, I'll do whatever reasonably possible to keep me alive. Starting a brush fire might not be the solution I would look for, but smoke can be seen for miles on the ground and in the air. I'd make every effort not to burn the forest down, but that's a minor consideration when it comes to my survival.
Glad they found this guy.
agreed, if you have the energy and conditions are right you can make a decent fire and throw a lot of fresh saplings on it for smoke. if that doesn't get attention then make the fire bigger i guess
