Would you rather be lost in the wilderness alone, or lost in a sea of people on a busy city sidewalk when nature calls? I would prefer to sort things out in the wilderness. Searching for that perfectly fallen tree and fresh leaves is a much more appealing scenario then using a seldom cleaned public restroom. At least in the bush there is never any worry of running out of leaves, and if the worst were to happen, there are no human witnesses. Being caught on a busy city sidewalk is an entirely different matter.
