Answer the question you selected for profile question 3 here (300 words):
When I'm out in the field collecting plants and surveying the biodiversity of an area, there usually aren't any bathrooms around. Emptying one's bladder in a prairie or forest is not a big deal, but you have to be careful to avoid ant piles, poison ivy, cactus, etc. One time I was so busy trying to avoid cactus that I failed to notice the stinging nettle I'd just squatted on! I won't forget THAT trip anytime soon!
