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

comment Can bears smell empty beer bottles?
@WedaPashi I am going to guess that anyone who is getting drunk in the wild is car camping, and not backpacking. And, in that case, it doesn't matter how heavy things are.

Exactly! Except a bear can probably smell them from a kilometer away.

comment Dog Breeds for Backpacking and Trail Running
@ppl I have never seen one before! I'll Google around. Were you thinking of them for running/backpacking/both?

comment What is the longest time you can go, eating only freeze-dried food?
@Marcus I suppose freeze-dried food would be high in salt. But they sell a great variety of it now. Assuming you have unlimited water, I see no reason you couldn't survive indefinitely.

comment Will using a sleeping bag stop the body from adapting to cold?
Adapting to the cold (or the heat) is a long process. I think of it as something I need to try to do in little ways every day. But when I go backpacking/camping I bring the warmest things I can, for temperature. Just IMO.

comment Will the benefit of an axe outweigh the drawbacks and win over a large knife?
Just to clarify, what situation are we talking about: backpacking? hiking and car-camping? General survival? (Perhaps we can clarify this and add a tag to your question?)

comment Dealing with rashes between thighs and around the groin
@Lathrop This is the exact solution I use. Loose boxers are the enemy on a long, hard backpacking trick or serious run.

Your link no longer works. Can we fix that?

comment Does eating snow help dehydration?
@RussellSteen I like math more than most people, but the experts have other practical information. For instance, the air-to-water ratio is the limiting factor in getting enough water from snow to survive. So, digging down deep in snow for a more compressed water source is vital to survival. I feel that should not be left out of the answer.

comment What are the major difference between a regular sleeping bag and one designed for women?
@OlinLathrop You are correct. I had my numbers backwards on that one. Thanks.

comment FiveFingers or hiking boots?
Just my anecdotal experience: Five Fingers make great hiking shoes, I love them. Unless I'm carrying weight. If you're backpacking you need a stiff-soled shoe to support the weight. You're feet aren't designed for carrying extra weight while backpacking.

comment How to Tell When Minimal Running Shoes Are Worn Out?
Oh no, I think the 'conventional wisdom' is just from experience. I know several runners personally who say that after you run enough miles in a pair of Nike's they start to feel like you're running with wood planks strapped to your feet. I think the rubber they use in modern running shoes just loses its elasticity.

comment How to Tell When Minimal Running Shoes Are Worn Out?
I think you're right. My minimal shoes seem to be lasting longer and I can't think of any good reason to trade them out.

comment Will barefoot walking harden the skin and help prevent blisters when trekking in heavy shoes?
I have noticed that walking barefoot only toughens the bottoms of my feet. So that won't help with blisters that you get in between your towns or on the sides of your feet/ankles. (Though, sure, it will help with blisters on the bottoms of your feet.)

comment Rappelling in the Rain
Ah! Thanks for the first-hand experience. I live (and climb) in Northern California on the coast, and the weather is a lot like England here. It rains like 100 days per year. I hadn't considered the lightning rod effect.

comment How tight should the line be kept for toproping?
@RussellSteen Definitely, I just wanted to mention the communication aspect. It's important. As far as safety, I believe DudeOnRock covered the issue of rope stretch well. With static rope (like in a gym) there is a wide range of safe slack. It's not something to worry about. Outdoors you'll frequently have more dynamic rope, and that is really the only situation where you have to actually think about slack. Climb safe, man.

comment How tight should the line be kept for toproping?
@RussellSteen The first couple times I belay for someone I ASK THEM how much slack they want. My lady never wants to feel the rope tug at her at all. But another friend always wants to feel a little tension, for his own mental security. Just ask. Similarly, you should expect your belayer to listen to what you want. That is their job.

comment What can I do with a retired rope and harness?
I love your link! Those are all great ideas! As a climber though, just keeping the old rope around (unused) can be a little dangerous. You or one of your friends might grab the wrong rope one day. It's best if the rope is clearly labeled as old, or used in an art project.

comment What is the most efficient food to take a for a 12-15 day hiking trip?
I agree. Dates are extremely an calorie dense, natural food, that is usually super tasty while on the trail. As a side note, try to vary your diet. If all you eat is dried fruit, you will eventually get the runs.

comment Logs & Rocks - Step on or over?
First off, there are plenty of hikes where I know ahead of time that there is little to no risk of poisonous snakes. In that case, protect your ankles. That being said, I'm sure it's safer not to jump on top of logs and trees, but I do it all the time. (I suppose, from experience, I estimate my risk being quite low there.) Now yourself and your surroundings.
