For some of us, morning coffee is definately a "survival" item. You would not want to be around me in the morning when I haven't had my coffee.

For years when camping I managed with a MSR white gas stove, a small filter cone, and some ground coffee. Then I discovered the Jetboil SOL and Starbucks VIA. Life is good!

(I still keep the MSR handy, since it works better in the cold, which has been known to happen around these parts.)
