Not all cold winter areas have snow. Picture high desert areas. The only water you have is the water you carry with you.
Yep. Exclude, for the moment, barren alpine and tundra areas (I've got a story or two to tell about THOSE and water - but another time). My time in high desert areas such as Yakima is limited to months, not years, and pretty much all of it non-recreational. Bring enough water.
Obviously we also agree about the wide mouth SS bottles...
