I must confess I have a problem with the word "ultralight" but we all kind of agree on what it means so it's a good placeholder word.
Something I've been noticing a lot lately that I never picked up on before is a difference in the way people who pack light think.
I think "Do I want to take this OR that?"
People who tend to carry a heavier pack think: "I'm going to take this AND that."
3 times I've noticed it in the last 24 hours. People taking windshirts AND rain jacket. Filters AND Aqua Mira, Neoair AND sleeping pad.
My mind just doesn't work that way. I just accept that I can't have everything I'd like to have - I'm going hiking, not furnishing an apartment - so I don't grieve not having a bunch of extras.
Big Note: I'm only talking about me. Not judging what anyone else carries - not even a little. This is just an observation I've made.
