I have heard many people who have this exact philosophy when hiking, but why? I understand going light to a point, I am sure most of us would do just fine with a bedroll, a lighter a, 1 liter bottle of water and some ramen. Tie the roll to your back with the food inside and there you go less than 5 pounds of gear, but we don't do this.
Now myself I take a lot of unneeded junk, like a camera, but I take these things to make my hike more enjoyable for me. I also only hike 7 to 11 miles a day, and I stop at every spot that looks cool.
Am I a minority in my belief that a good hike involves what I saw and did, not how far I went or how fast I did it?
