comment Is it safe to drink out of rusty thermos?
@berry120 I wouldn't risk it on any normal day. But based on what Dr. Wife told me, I guess it would be safe and I would do it in a more emergency/dire situation.

comment Are there Latex Free climbing tapes
@Jean I believe this is a good option. Their description of the product as being cloth without discussing any plastic, waxy, or slippery coating makes me think it would be ideal for gymnastics and climbing.

comment Belly flopping top outs
If you are at all concerned about the height of a top-out while bouldering, or feel you are not in the best position to stay on the rock, belly-flopping the top-out will give you a LOT of friction to keep you on the rock. Safety is important.

comment How to carry dslr camera when rock-climbing
@DudeOnRock I am still interested in seeing this question answered. The only solutions I've come up with so far are: take a point-and-shoot instead of a DSLR, and bring a big, fuck-all camera backpack with all your gear. I wish there were a tiny, minimal, well-padded backpack for DSLRs.

comment Is it realistic to teach yourself rock climbing?
I am an avid rock climber and have a couple thoughts. First, you will need to climb with a partner so you might as well find some experienced people to climb with. Second, I've met two kinds of climbers: those who does everything they can do to stay safe, and the reckless. Guess who gets seriously injured more often.

comment Abandoning a multi pitch climb
@Liam When first learning to multi-pitch climb, it is very important to: climb with more experienced people, read books on the subject, and take a training licensed course (which you can find a places like universities, the Sierra Club, and REI).

comment How to get started skiing?
@nibot Assuming you mean downhill skiing, you need: water proof (Gortex) pants, warm gloves, and a warm coat. Rent your skis, boots, and poles until you know more about skiing. (Wool socks would be a plus.) Strategy: do NOT learn the "pizza and french fries" method, just learn to carve (turn regularly to slow your speed).

comment Do you need to purify all mountain water sources
@Liam I think mountain water is pretty safe. In California, we are careful that there aren't any cattle ranches up stream. But other than that, mountain water is pretty safe for backpackers. (My wife is a doctor and wants me to remind you how easy it is to purify your water anyway.)

comment How do I prevent rocks or sand from getting in my boots?
Interestingly, I don't have this problem and I hike a lot. I wear serious, heavy-duty, thick-soled backpacking books, laced up the ankle. And I wear thick wool socks.

comment Flashlight or headlamp for night hiking?
I prefer headlamps a great deal. I need my hands to do things.

comment Are headaches a bad sign at altitude?
Thanks so much. For some reason, I am particularly susceptible to altitude, but none of the people I regularly go tromping around with are. I just want to make sure I'm not being too stupid.

comment Are headaches a bad sign at altitude?
@Ben I always get headaches when I go above 9000 feet elevation. To your points: I slept well the night before, I ran a marathon a month ago so I'm pretty sure it's not "aerobic challenge", and I don't drink coffee. I live at sea level, 9000 feet gets me.

comment Warmth of two sleeping bags
My GF used two sleeping bags in Yosemite this winter, and thought they were over-the-top insanely warm. So, based on that one-time experience, I believe it would be closer to a -10-degree bags.

comment Lowe Alpine - TFX Cerro Torre: pack is moving to sides
Do you know how to adjust all 6 straps on a modern backpack? That also might make for a better question in this format: one that would be more generally useful to a lot of people. Just an idea.

comment What is this knee pain when going downhill?
I am not a doctor. But I have found a solution to my knee pain (which I think might be the same area): a lot of leg strength exercise. If my quads are strong enough, I can walk down hill (with a heavy pack on), landing heel first. This takes the pressure of my knee, and I can walk faster. Again, I am not a doctor.

comment Rock Climbing - Beginner's Guide for Quick Improvement?
@bhekman I forgot to mention the mental game. ESPECIALLY if you want to climb outdoors. Work on your fear. Put some serious effort into maintaining focus when you're in a tenuous position or are very tired. The more effort you put into this, the better you'll climb.

comment Why does my belay device have two holes?
Rapelling. You will put both sides of the rope into your device when you rapel.

comment “Must Have” in a starter Trad Rack
A friend once told me that you shouldn't buy any gear until you know what climb you're doing, then buy the gear for that climb. (As a starter, a set of nuts costs little more than a single cam. So I just bought a set of nuts.)

comment How to warm up your cold toes and fingers?
Bonus points to anyone that can answer this question for rock climbers. There's nothing worse than trying to climb on frozen fingers.

Finger boards are key. If you follow a plan, and are careful to not over-train or hurt yourself, fingers boards lead to Fast Gains. Be careful and be smart. But finger boards are key.
