I got a Camelbak for Christmas-- a gift I'm very excited to use once hiking season swings around again. The one I got is the same model and nearly the same color as Adrien's though, so I thought that I'd differentiate it from hers by embroidering something special onto it.
I picked a Dwennimmen, an Andinkra (in West Africa) symbol of humility and strength.
I picked it because in order to get by in the wild (or anywhere, really, but since this applies to hiking...) one must be strong but also recognize the strength that you have and realize that with it come responsibility, humility, and (hopefully) an awareness of the earth around you.
Anyway, here's a picture of it on my 'Bak:
I'm such a nerd.
