......Be interesting to see how a group of us, say 8, survived with just 1 litre of water for two days. We take water for granted for the most part... its all too easy to turn on the tap. Given a situation where the tap isn't an option, and lets say for arguments sake the purification straw is broken... who would be thirsty after 48 hours.
I'd wager I'd be a thirsty one given my current knowledge.
In moderate weather, say below 75f (21.1c) I get thirsty after an hour; two at the most. In warm weather and with a bit of activity? Every half hour or so. But as my earlier post inferred, I carry less water than it appears y'all do. Well, sorta anyway. I usually try to have a 3 gallon water cooler in the truck; but when hiking I've never carried more than 2 quarts (whether in 2 separate 1 quart canteens or in a single 2 quart one) Not even on horseback when I obviously had a higher weight tolerance, nor in the desert. Apart from the desert, I always try to camp near water.
