Thanks!! I just got back from my journey, and for the sake of experience and my bowels, chlo-flor tabs worked well, although the filtering process involved is a pain in the buttocks!!! After two of the five days, I skipped the overkill method and just went with the water filter. No illness to speak of yet!! I'll keep you posted. By the way, I had a blast! Also, a personal thanks to Chris, I made it on my own, man!<br><br>
