Good tip PODS, I am heading out to teach whitewater guide school on the 20th and will spend 11 wet and rainy days in the Fleet, I think I'm going to set out a tub of that in the camper for the week. Is it safe to have out while you are in the camper?
It doesn't pollute the air or such if those kinds of concerns are what you are thinking. When I've gotten the liquid on my hands its feels a little slimy but washes off fine. I'd mainly be worried about kicking it over, etc. I see a dog in your avatar picture though, so I'd double check on whether its toxic if ingested (they have an MSDS on the site).
I don't carry the stuff when camping just while in storage after I've aired it out so it pulls out moisture that may come in or may have built up. Its a gradual process so I don't know how it'd work in a camping situation with lots of moisture being added but its worth a shot if it doesn't get in the way.
