threads dying, but...
Anyone out there carry tea tree oil?
I find that when I'm scratched up, dusty, grimy and downright not feeling as good as I should after 2 or 3 days - I drink some water and apply some tea tree oil to a babywipe or a damp washcloth to clean the face, pits, and parts. You can also apply it to a cottonball for scratches and cuts (it's a minor antiseptic, and I read a study that suggests it helps prevent MSRA staph). And, if the sinuses act up or the hiking partner reeks on the ride home, put a dab on the inside of your nostrils. Lastly, it's a decent-to-mediocre bug repellent.
Duct tape = yes, with a but: exempting short trips.
