I'm a physicist modeling air pollution and global warming.
Of course, I spend most of my time programming.

comment How to harden feet for walking barefoot on harsh surfaces?
I have done a lot of barefoot running. You can train your feet to do a lot of things. But at some point the temperatures of concrete on a hot summer day will burn your feet. You can't get around that. Humans weren't designed for concrete. You can train for rougher surfaces, but not so much hotter ones.

comment Why go without socks with climbing shoes?
@ntc2 Good point, I added that detail in.

comment Could smoking pipe tobacco or a cigar attract bears and/or other wildlife?
@manoftheson The idea here is that the smell of smoke might attract a curious bear. I have seen bears approach camp fires almost a dozen times while camping and backpacking: do not make the mistake that smoke will ward off bears or coyotes.

comment Vibram FiveFingers, useful, gimic?
@Liam Comfort. For walking, or any run under 12 miles, they are the most comfortable shoe I've ever owned. By far. The major downsides were: the un-cleanable smell, and the fact that every idiot in the grocery store would ask me about them.

comment Vibram FiveFingers, useful, gimic?
I LOVED my Vibram Five Fingers. But my partner complained, rightly, that they stank horribly. Now I wear the New Balance Minimus. For really long days, like running a marathon, the Minimus are slightly more comfortable, because they don't have to be as tight.

comment FiveFingers Spyridon for Climbing?
@NatureRules I just ran a marathon in my Five Fingers. I love them. I also love rock climbing. Do NOT wear the Five Fingers for rock climbing. Actually, you would figure that out yourself after about 20 seconds of hard climbing. They're the worst.

comment Pink Winter Sleeping Bags
What is the correct way to link to gear on Great Outdoors? I feel like this will be a problem again in the future.

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.
