19844Re: I'm seriously considering leaving my water filter at home next summer
- Jan 2, 2012Gotta say I very rarely treat my water, but I am selective as to where I get it. As I recall, Peter speculated that he got sick from Sunrise Creek.
I avoid drinking down stream from any popular camps, lakes or other popular areas. I pretty much stick to springs and other sources coming from less visited areas (which there are plenty to choose from).
That system has worked for me for 40+ years; it may or may not work for others.
