comment How to stay hydrated with minimum water usage
@David: You may not live or routinely hike in a desert but lots of people do. For many, it is the common case. Also, this is rebutting the OP's friend's blanket statement of 100 ml/h being enough, which supposedly covers all cases. It only takes a single example to prove it untrue. It is irresponsible for lots of cases, and borderline at best for the right circumstances.

comment How to stay hydrated with minimum water usage
@gerrit: I agree there are conditions, particularly rainy and cold but above freezing like you describe, where 1 l for a 10-hour hike is certainly possible. And, if you have regular access to water, then bringing a single 1 l bottle is fine. However, I certainly wouldn't recommend that for the general case, as the OP seems to be asking about.

comment Where in the US can I find green mountains to hike like in Scotland, such as Dalveen Pass?
You say GB and UK are used interchaneably, which confuses me. Isn't the UK a sort of association of countries, like England, Scotland, and a few others? For example, isn't Northern Ireland part of the UK, but not on Great Britain? Doesn't UK also include a few Carribean islands, and used to include a lot more? So how do you refer to the geographic island that contains Scotland, England, and Wales, in contrast to the political entity that is the remnants of the once far-flung empire which today is largely, but not exclusively, found on the island of Great Britain?

Nits: You meant to say same latitude. UK is a country. The island you are referring to is Great Britain.

comment What are the different methods to purify water?
By the way, I wrote the firmware for the SteriPen Ultra. It has a display that counts down the seconds so you know how long to keep it sterilizing for. If I remember right, it takes 90 seconds to serilize 1 liter of water.

It would help if you showed a picture of the kind of landscape you want to hike in. No, I don't know Dalveen Pass, and I expect few others here do either. Also, which attributes exactly are the ones you care about. Openess, grass covered, the typical temperature, wetness, windiness, etc?

comment How precise is a pedometer for estimating on a backpacking trip?
@mjr: No, a "pedometer" is something that tries to measure footfalls or steps. GPS units can measure traveled distance too, but it is wrong to call such devices "pedometers". You could use a measauring wheel to find trail length, but again, that's a measuring wheel, not a pedometer. In other words, pedometers are always step-based trackers, as you put it.

comment How precise is a pedometer for estimating on a backpacking trip?
Whether the GPS accumulates distance while you are standing still depends on how you have it set up. Normally you have it not create a new point until it thinks it's some minimum distance from the previous point, like 50 feet. Measuring a trail in 50 foot straight sections is still plenty accurate enough for most purposes, doesn't suffer from sitting still jitter, and doesn't accumulate ridiculously large GPS tracks.

comment What are some good guides to the U.S. national forests, specifically those in California?
@Jason: They are next to each other, so I'd bump around and experience the variety myself. Like I said, one plan might be to start in Westwood and hike around north of there one day, go more north or east and hike around there the next day, etc. After a few days you'll end up in the NE corner of CA and will have experienced a wide range of different landscapes, but all relatively dry and open. Dig around Google Earth and look at uploaded photos.

"Lassen" is also a National Forest.

The existance of stupid people doesn't make your statement, "the Canada part of the USA" any less stupid.

"The Canada part of the USA" Huh? Perhaps you meant the Canadian part of North America? Remoteness is certainly more abundant in northern Canada than in the 48 states, with parts of Alaska also be quite remote.

comment How can I avoid an encounter with a large feline?
The traditional method is to bring along a goat. When the tiger charges, release the goat and the tiger will go after it instead of you. I imagine a small skittish person would work in place of a goat.

comment What fictitious wilderness animals are there as tourist attractions?
My personal favorite is the Jackalope that inhabits the dry areas of the western US. You run across them from Arizona to Montana.

Geesh guys, lighten up a little. I wouldn't say every myth or fictitious thing is OK here, but this one seems pretty harmless, and rather fun too.

comment When should you carry a firearm when hiking/trekking?
The AT will be well known to anyone trying to hide illegal activity in the woods. You're simply not going to stumble on something like a marijuana farm on or near the AT.

comment Is it possible to put a kayak in the water in Berlin and reach the Baltic via lakes and rivers?
The Havel and Oder rivers are linked by canal. Also I know that my grandparents did it regularly in a small boat in the 1920s and 1930s.

comment Black bears and torch lights
@Russell: The numbers on predatory bears is higher than what I remember from a earlier study, but you still need to keep that in perspective. As the article says, there are millions of encounters between humans and bears, and only a very small fraction result in injury. Since 1960, the average has been one such death per year. Compare that to over 40 deaths per year in the US from getting hit by lightning.
