NiytOwl: I had to chuckle. But to answer your ‘question’, none of the spots are in the same place. Some are at belt loops, some are at where the zipoff zippers connect; some are on the rear. Hmmm

CamperMom: you may be onto something. I use a sunscreen that is combined w/ bugspray. I’ll have to experiment on those lines…

Drow42: I don’t use chemical water treatment. I just use a filter. However, after I’m done backpacking, I do clean the filter with a couple drops of bleach. Hopefully I don’t get little of the solution only on my khaki pants; otherwise, that’s quite a coincidence.
