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

comment Chaining locking carabiners
Thanks for your answer, but this doesn't really address the question. What you're describing is essentially what I used to do. The question explains what I didn't like about that method.

I also don't understand the remark "just go buy a quickdraw." I own some quickdraws, but I don't see how that's helpful here.

comment What are the rules to grade sport climbing single pitch routes?
I really think it's purely subjective. There are lots of different ways in which a route can be difficult, and they're not directly comparable.

comment What is a good substitute for water purification tablets
Depending on where you're going, water purification may be totally unnecessary. For example, the scientific evidence shows that backcountry water in the Sierra is safe to drink without treatment. Different methods of purification also handle different types of bugs. So the place to start would be to tell us where you're going, then we could figure out if there are any nasties that need to be killed off. Then if there are, we could suggest a method that would work on that type of nasties.

6 mm perlon cord is cheap and should work.

comment Chaining locking carabiners
@requiem: Interesting. I've never seen those. Are you thinking that they're intended for linking together two carabiners? But I can accomplish that by just winding a shoulder-length sling five times around my hand. That gives me something about 4" long. (It's awkward to try to get it any shorter than that, because of the bar tacks.)

comment Chaining locking carabiners
@Dakatine: Interesting. But I don't have any reason to carry a daisy chain, since I don't do any aid climbing. (They're no longer considered safe for use as personal anchors.)

comment Chaining locking carabiners
I think you're misunderstanding the question. I'm using this to extend my ATC so that I can fit a Prusik backup underneath it. I'm not talking about using it on the anchor that I'm rappelling off of.

You know those chemical heat packs that they sell as hand warmers to put inside your gloves? If you're male ...

comment Benefits of tree tents over typical shelters?
It looks like a cute concept, and it might be fun to do. But what do you do on a multi-day trip when some of your campsites don't work for this technique (e.g., you're above tree line)? What if the trees aren't big enough to handle this amount of tension?

comment What is an effective way to join a map that is printed on several sheets?
A single larger sheet is not necessarily better in every way. I've bought a bunch of USGS maps that are in a large format, but when I fold them up they are bulky in my pocket, and it's awkward to pull them out and look at a particular area without having to open up the whole sheet.

comment When is it too cold for Tarping?
I think of tarping mainly as a technique for ultralight summer backpacking. If you're in snow, a tent lets you keep everything dry. A tent will also keep the wind off your face while you sleep.

comment Dropping gear: Where did the hairline/micro fracture urban legend come from?
Are we talking about dropping a carabiner from waist height to the ground, or are we talking about dropping it 100 feet? I can't remember ever dropping a carabiner. Carabiners are what you use to prevent dropping other things.
