That’s my mantra and I’m sticking with it. Mrakun misses the point. Of course there are literal small accidents that may have little or no consequence. But if you’re backpacking, then you probably don’t have immediate access to 911 help or rescue. Accidents and their consequences are MAGNIFIED by the seriousness of the injury/accident and the distance to rescue or appropriate medical attention.
Somebody who is walking in the woods, no problem; but, somebody running in the woods, with a pack, and then again in the dark, literally hours from walking out, has just multiplied the chances of having an accident, and possibly a serious accident. Somebody who has a turned ankle and can’t walk out on their own, that’s not small in my book.
My mantra is advice to be careful and consider the consequences of your actions, further, to conduct real quick risk analysis as you walk, cross a stream, tightrope a wet log over a rushing creek, try to down climb/rock scramble, even leaving your sleeping bag out of the waterproof bag or going into the woods without a map (or not knowing how to use them).
Backpacking is a subset of Mountaineering, whether you intend to ever climb a mountain or not. All the skills are transferable. Even the skills of critical thinking (whether one is aware or not), to understand risks, identify objective dangers and learning how to plan, are applied to both backpacking and mountaineering.
Every single skill you perfect in the woods of Virginia can be applied to the mountains of Colorado or Switzerland. With the exception of roped glacier travel, rescue, and avalanches, all the skills necessary in the forest apply, e.g. Layering to stay warm and/or dry, sleeping, camping, cooking, first aid, navigation, route planning, leadership, etc, etc, etc..
So lighten up, you’re probably ready to start mountain climbing and don’t even know it.
