Good luck and all, but I'd be careful as a all hell setting of a flare gun/aerial flare in the forest! You have absolutely no control where the damn thing will go with a high potential of starting a forest fire. Flare guns are good for the deserts and the seas.
Believe me if you set off smoke flare in the forest and someone is looking for you in the general area, they would have to be blind not to see it.
Lots of good stuff in this thread.
