[pct-l] Giardia Lamblia - Excellent informative article by Robert L. Rockwell, Phd

[Ken Murray]

"While I am not aware of any double blind, peer reviewed studies,
several anecdotal surveys have shown little correspondence between how
fanatically a hiker treats his water, and how likely he is to contract
Giardiasis.  That being said, you can be afraid of whatever you want
to be afraid of."

I am reminded of a trip into Rockhouse Basin 6 or so years ago.  I did not treat the water.
One of the guys on my trip GOT GIARDIA, and I felt bad about it.....until I realized that
he was the only one filtering the water.......
