I don't think anyone is suggesting that they'd be prepared for everything. I do know that I've spent enough time in the wilderness that I could survive on my own for a couple months, if I had basic survival gear (knife and flint). Like I said above, if the first night is rainy, that would be the toughest. If it was dry I'm pretty sure I'd be fine for a while, until either help arrived or I decided to start hiking and start searching for civilization.
