Answer A: What are good designs for volunteer-buildable trail bridges?
The Swiss have detailed documentation on this. You might not understand the German but the sketches are fairly clear. Two things you might want to know: the introduction says the type "A" ones should be designed by a competent engineer, but the type "B" ones are easy to build. Any sketch labelled w...

Answer A: Are there any reliable plants to use for navigation?
For a book-length answer, see Tristan Gooley, The Natural Navigator. The gist seems to be that plants are influenced by many factors: altitude, prevailing wind, soil type, shade etc. so any rule will at best apply under certain conditions, and even then have exceptions. One of Gooley's examples is ...

Answer A: Can the Swiss Alps be hiked in the winter?
The normal hiking trail network is meant to be used, in a rough translation from the German specifications, "during the snow- and ice-free time".

Answer A: What is the fastest style of sled?
You can have the fastest Rodel (see fgysin's answer), when you come to a bend you'll have to steer and that means braking with one foot, slowing you down overall. So I give you ... the ghosky: You can steer it by leaning to one side making it "carve" like a pair of skis. Youtube video of it in act...

Answer A: Would tied strips of webbing have similar strength to a climbing rope?
A climbing rope, as in sport-climbing, is also known as a dynamic rope - it stretches when you fall. If you use polypropylene strips and fall 5 metres, even if they are strong enough not to break, the same force acts on your body as if you fell 5 metres onto solid ground. If this weren't a problem, c...

Answer A: What are common rock-climbing footwork mistakes and how I can spot them?
The mistakes I mention might be more common at lower grades than yours, here goes anyway: Too big steps. When I started climbing I tended to make massive steps, leaving out many good footholds in between. A more experienced friend taught me to avoid this by clipping a quickdraw between my climbing ...
