We often see hikers showing up to hike with a low-level or no-level of skill sets for the intended journey. Let's make a list, so to speak of skills one would do well to study or be accomplished in BEFORE attempting a thru hike. Do not include any "skills" one would not necessarily need before attempting a thru hike. Of course, this is all subjective. One might think a hiker should be proficient in say "knot tying" where others and myself included would not. One might list "make a fire" where I would say that is "old school". This would be interesting and might be fun and promote more preparation for backpacking. OK, as an example here is a short list:
1. Proficiency in Map and Compass
2. Proficiency in using GPS with Map and Compass. This would include being able to take coordinates of your location from the GPS and transfer it to the map you hold.
3. An ability to know where to find water and how to obtain clean water.
3. Specialized ability to do effective treatment and care for one's feet.
