If you REALLY want to make it in the backcountry, there are really only 3 things you need.
Brains, balls, and enough experience to know which one to use.
The last one is tricky of course, but that's why you should be honest with yourself before planning a trip and know what your abilities truly are. Then plan your trip based on that. When I first got into backcountry sports, I would run into the old crusty hikers and climbers that looked (and smelled) like they lived there.
Today it's GPS guided, solar showered, eco friendly, metrosexual, yuppie pantywaists from Seattle that come clanking down the trail carrying huge packs full of brand new gear bought from a catalog, half of which they will never use, trying to prove that they are still men, and failing MISERABLY!!!!!!!!
Ok, I'm done now.
