Nice. Ill have to try that on my friend and tell him its a Mosquito repellent.
In a pinch you use some as a fire starter or candle.
I think butter would be better. To help keep your self warm light a fire below you. Oh and cover the top of you with some salt, pepper, and rosemary as a TQ. Try to slowly keep rotating in your hammock at a slow steady speed for about four hours. mmmmmm tasty!.
Least its water Proof.. Will not need a Tarp.
