Thanks, Jason! "Visual pollution" is the term I wanted to use, but I had a "senior moment" while writing my prior post. It applies not just to women's wear and gear (although we women have an additional reason to want to be inconspicuous) but to those bright orange and bright yellow tents, too! They may look pretty from inside, but they look horrible dotted about the landscape! I like my gray silnylon tent; it's plenty light enough inside and blends into the landscape from outside.

Earthling, I found the .5L Platypus currently available at both Campmor and the platypushydration.com websites. It seems to no longer be called the "Li'l Nipper," but it looks like the same bottle with the push/pull cap as the one I have, which I bought in 2000.
