I remember you from when we used to meet at Pet Paws in Plainfield and know that's not the type of person you are.
I had a Sawyer In-Line filter a.k.a. the mini filter in my pack inside a Nalgene bottle with a Steri Pen and extra batteries if I really needed it. I keep a bandana in there also to help filter out larger items in the water so the Sawyer filter won't clog as fast. Everyone in the house has a Sawyer filter in their bag but I still need to invest in a few more Steri Pens.
