This page is about how much you REALLY know about the areas you will be spending time in.
Is your knowledge just from books? Have you learned everything you know from Internet Websites? Have you been hiking in places similar to this? Did you grow up in this type of terrain?
Don't overestimate how much you know (especially if it is all from books and websites). I say this because what you will find in the field is DRASTICALLY DIFFERENT from anything you will find in books or online.
