Well, what happens if you are out in the woods and you run out of trioxane? Any ideas what to look for then?

I gotta say it again I reckon. Anytime I am out in the woods for any length of time, I have a habit of collecting tree pitch. I really like Spruce and Douglas Fir. It is fairly easy to find if you know what you are looking for.

It kinda depends on where you are, though. For instance, I don't have many trees around here, so collecting pitch locally is not realistic.
