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

comment What are the advantages of a double sleeping bag?
Another possibility, advocated by Ray Jardine in his book Beyond Backpacking, is a down quilt.

comment How to take care of steel crampons?
@Stony: Interesting. First I've heard that there was any controversy. Can you point us to any online or print discussion?

comment Large Tents and Traditional Campsites
It seems like you have contradictory requirements. A tent that you'd be comfortable living in for 2 years is not going to be a tent that you'd take on a weekend car-camping trip.

comment What's the difference between Sport Climbing and Traditional Climbing
Nice answer. Another way of stating the distinction is that trad is more of an outgrowth of mountaineering, and pretty much everything you do in a trad climb is potentially something you could do while mountaineering. Sport climbing, on the other hand, is more about gymnastic skill.

comment What's the maximum temperature difference wind-chill can account for?
The table doesn't really "level off" or flatten off It doesn't absolutely flatten out, but it does relatively flatten out. For example, take a look at the -20 C column of the table you linked to. Going from 10 km/hr to 20 km/hr produces a change of -3 degrees. Going from 50 to 60 km/hr only gives -1 degree. It doesn't become completely flat, but it does flatten.

@dspyz: I think you're taking the physics and mathematics behind the formulas more seriously than they deserve to be taken. They're just smooth curves that people dreamed up.

comment Trekking poles: Collapsed or fixed?
@QuentinUK: All kinds of things could be more or less important to different people. It's just a matter of personal preference and style. Since it's a matter of style and preference, there isn't going to be any objective answer about some fine point of how to use them.

comment Is there a definitive list of the tallest mountains in the world that require little or no mountaineering experience?
@Qwerky: Kilimanjaro yes. Mt Kenya no. Mt Kenya's twin summits are class 5.

comment Trekking poles: Collapsed or fixed?
It's doubtful that trekking poles are beneficial at all: outdoors.stackexchange.com/questions/4470/… Since there is no clear benefit at all, I don't think there's any way to say whether the putative benefit is optimized by adjusting their length in a certain way. The optimal benefit might be gained by throwing them in a dumpster.
