You still got to get step into the woods for a bit. A good learning experience I'm sure. Next time around will be better. Sorry you missed out on the steripen. We used ours this summer while kayaking in Alaska. Prior to that we had wondered down to a spring fed creek at the back of my parents property for our first testing. Used a homemade filter for the big stuff (dirt, leaves and such) and the pen for the important stuff. I love it and I'm sure you'll be happy with it. Good luck with your future trips.
"Mother Gue", I says "the Rocky Mountains is the marrow of the world," and by God, I was right. Keep your nose in the wind and your eye along the skyline.
