I live at 6300 feet and regularly ski over 9500 feet in winter months, In summer I sometimes spend couple of days up to to a week hiking. And I consider myself a puppy to some folks I meet. If I could carry more food, that would be great. In all my time of enjoying the mountains I have never had the need of a multi purpose tool or a tent. My Mora knife, which is carbon steel and not stainless is by far my best friend. Don't solo until you are really knowledgable about what you are getting into. To preach solo is not a smart thing to do.
