Going to be in an ELK CAMP in NW WY abour 4 miles from yellowstone. I am told taht the outfitter has used this camps for at least ten years and gets his water out of a Spring near the camp and has done so for several years and has never had a problem!

My question would you trust this or would you still filter the water! I have a new MICRO filter that I plan on taking!

I have gotten sick before and REALLY Dont want to ever go there AGAIN!

ADVICE PLEASE
