What are the pros and cons of cotton vs mesh filters for making cold brew coffee in a Nalgene water bottle? From my research so far into making cold brew coffee in a Nalgene while backpacking, I have found there to be two types of filters, cotton ones called "coffee socks" and mesh ones that screw onto the top of the bottle. I like the idea of cold brewing because I fairly often don't bring a stove, and I... (more) |

Is there an actual advantage of switchblade folding knives over any other method of opening a folding blade with one hand? More states in the US are decriminalizing switchblades, yet there are many other methods of opening a folding knife with one hand such as studs on the blade or groove to make it easier to open. I am not talking about the ones that have double edged blades but rather standard folding knives such as t... (more) |

A: Is it generally safe to hike a pass in a thunderstorm? The pass is safer than the peaks on either side of it, but less safe than not hiking over the pass.

How is the maximum legal altitude for campfires determined? In most national parks in the United States, campfires are prohibited above certain elevations (9,600 ft for Yosemite,10,000 ft for Ansel Adams with exceptions). This is a good thing because after a certain height the trees don't grow fast enough for campfires to be sustainable. Do note that this a... (more) |

A: How do fly fishing lures work? For fly fishing, there are two types of flies, wet and dry. The wet flies are designed to sink and bitten by the fish underwater, while the dry lures are designed to sit on top and the fish will come up and bite them. If you are really lucky the fish will leap out of the water to do so. The short v... (more) |

A: How do forest fires affect rain run-off? Basically it increases the runoff in a number of ways, less soil cover in the form of vegetation, ash blocking the water from being absorbed, and in some cases a hydrophobic water coating can be left behind.

A: Reusing disposable water bottles vs. buying dedicated bottles The problem with using the cheap bottles is that if they break, you can be in serious trouble. A quick price check says that 32 oz nalgenes go for around 10 bucks and 2 liter hydration bladders for around the same, so are you really saving that much money for the extra trouble? I have seen Nalgene 3... (more) |

A: How do I weave the backpack shoulder straps when there are two strap adjusters? You would only want to use one of them at a time.

A: Is there any evidence that black bears (or other large predators) are indifferent to, or acutally repulsed by, the scent of humans? For certain, bears noses are good enough to smell humans, whether that is a deterrent or a sign that unsecured food might be nearby probably depends on the state of bear-human relations with areas like Yosemite where bears are used to humans being different from places with hunting.

What conditions would make a weather inversion likely? An inversion in weather terminology is when the temperature actually rises with altitude, instead of decreasing like it usually does.
