Water...
SoCal is using water faster than reservoirs are filling. I'm not an alarmist, I'm certain that there will be water at my tap when needed in my lifetime, but it's going to run out eventually.
I just read this article, made me think a bit about my water usage.

I've converted my front yard from grass to cactus and succulents that are all drought tolerant. My back yard isn't that big, mostly drought tolerant plants on the terraces, and a 30'x80' patch of grass that I do my best to keep green. Dogs and grandkids are hard on the grass, but it usually looks decent.
I drink most of my water from plastic bottles. My wife doesn't care for our tap water, even the filtered stuff out of the 'fridge. I think I drink from the plastic bottles just because of their convenience. At work we have a filtered water machine that I get my water from...in a Styrofoam cup! For whatever reason it has never occurred to me to try a reusable water bottle.
Just some food for thought.
I'd guess that a pretty good percentage of the people here are already doing this. What do you guys use on the trail? I usually freeze my water bottles, I like my water cold. Any tricks other than getting the larger size water bottles? I'm not looking to go suck water out of a gutter and filter it to make it drinkable. Taking a shot at doing my little part to help with the plastic bottle problem.
