I live in LA and enjoy day hikes, backpacking, rock climbing, and mountaineering.

comment What to look for when purchasing a fixed blade knife
Yes, links are fine. The only thing that's frowned upon is answers that consist only of a link, so they don't stand on their own.

comment What foods can you cook by directly placing them into a fire?
If you don't want to wash dishes while camping, use freezer bag cooking. This will also have the side benefit of preventing diarrhea caused by bad potty hygiene and hand-to-mouth contamination from your hiking partners.

comment Taking Aspirin in higher altitudes
Disguising the symptoms of AMS is not necessarily a bad thing. At moderate altitudes (say 3500-4500 meters), AMS is typically just a nuisance. If you can make the symptoms go away, that's great.

comment Altitude sickness when going from sea level to 14,000 ft (4,200m) in a single day
A lot of what people interpret as AMS is actually sleep deprivation and caffeine withdrawal. Re caffeine, see Hackett, "Caffeine at high altitude: java at base camp," High Altitude Medicine and Biology 11 (2010) 1, and this question: outdoors.stackexchange.com/questions/5820/… . Diamox is a good idea if there's time for her to get a prescription and test it at home to make sure she doesn't have a bad reaction to it. It's rare to get dangerously sick at 14,000'. Most unacclimatized people will simply feel lousy to some degree. That's all AMS is.

*Regardless of what you do, hydrate, hydrate, and hydrate. * "While symptoms of dehydration are similar to AMS, no compelling evidence suggests that dehydration contributes to AMS." -- Hackett, "Caffeine at high altitude: java at base camp," High Altitude Medicine and Biology 11 (2010) 1.

I don't think it's true that you have to use diamox for weeks while gradually acclimatizing to ultra-high altitudes. I often take it the night before summit day if I'm going to ~14,000'. But you do have to be careful because diamox makes some people violently ill. It's a good idea to try it at home to make sure it doesn't make you sick.

comment Making a Make-Shift harness from Tape-Slings
@Andrew: No, it's the other way around. A real climbing harness is much heavier and bulkier than this type of harness, which is just a loop of webbing plus a locking carabiner.

@goldilocks: What is the point of the bag cover if you have dry bags inside the pack?

In addition to what pheidlauf said, getting your feet wet makes the skin soft and therefore leads to blisters. That makes it even more crucial to have dry socks and shoes.

comment Group camping - cooking equipment and eating utensils packing list
Communal cooking/eating combined with bad potty hygiene is apparently the main cause of backpacker's diarrhea (which for decades had been blamed on contaminated backcountry water). Your safest bet is individual cooking, which can be done easily and conveniently with the freezer-bad cooking technique. More info here: lightandmatter.com/article/hiking_water.html
