comment How much water should be carried while hiking in the desert?
Hiking around Mt Lemmon is rather different from hiking on the basin floor.

comment How much water should be carried while hiking in the desert?
Where exactly in the "AZ desert" are you planning on going. Some places are a lot more severe and remote than others. For example, deep in the Kofa NWR, I'd be extra careful.

comment What is a place in the U.S.A that is between 40-60 degrees year round and doesn't get a ton of rain?
Yes, Eureka is quite rainy, as is everyplace on the west slope of the costal range in the pacific northwest. In fact, that's where some of the highest rainfalls (and snowfalls) are recorded in the US. There is a similar but smaller region in Hawaii, which I think has the actual highest rainfal in the US if I remember right. The highest snowfall, again if I remember right, is at Paradise Ranger Station on the west slope of Mt Rainier.

comment What are good designs for volunteer-buildable trail bridges?
@Dopey: As you point out, making it wider would require significantly more strength of the horizontal decking, which would add significant cost. There is no point to a bridge that can support a wheelchair or stroller when the rest of the trail can't. We wouldn't use this bridge for the "accessible" trails in town, but those are seriously more expensive and require a budget all their own. The majority of trails will always be regular trails for that reason. It is simply unreasonable to make all the outdoors wheelchair-accessible.

@ppl: If something added cost so that it is 1/3 the final cost, then it added 50% to the original cost. It's two ways of saying the same thing.

comment What is the longest time you can go, eating only freeze-dried food?
A normal fit person can go without any food for longer than two weeks, so clearly the two week limit on freeze-dried food is bogus, unless you think eating freeze-dried food is actually worse than no food at all. Take a look at how long people on hunger strikes have lasted. The answer is much longer than two weeks.

comment Flashlight or headlamp for night hiking?
If your headlamp is shining on the top rim of your glasses, then you have a poorly designed headlamp. I arranged the LEDs on my hat carefully so that none of the light gets into my eyes or on my glasses, but the hat rim causes no shadow within the normal field of vision. Having the light forward, like on the hat brim, helps with this. As for a flashlight as a club, the extremely slight advantage is far outweighed by having to carry a large and heavy club. In all the time hiking in my whole life, I've never encountered a situation where a club for defense would have been useful.

Avoid stepping on the glowing gooy stuff.

comment Flashlight or headlamp for night hiking?
I don't get the part about the brightness of a headlamp effecting your vision. The light from the headlamp shouldn't be shining into your eyes or onto your glasses, and yes, I do wear glasses. If it's foggy, then having a light not near your eyes, like a flashlight, is useful. But in normal conditions I don't see the issues.

comment Walking through a Thigh-high snow
Thigh-high snow and 30 degree slope sounds like a dangerous combination. You're just asking for avalanche trouble. Then the 20,000 foot altitude will make rescue much less likely.
