I am so grateful to The Trek and it’s glossary, it’s helping me prepare my 2018 Thru-Hike. As a novice to hiking my research expanded my vocabulary exponentially. I still thought folks carried metal canteens, lol! How about adding to the glossary a section devoted to gear terminology? Words like: denier, cuben fiber, brain, fly, ridge line, A frame, to name a few. As a newcomer I was thinking it would be nice having one place to go to to learn what these terms mean in the hiking world.
I’m with ya Sport Jensen!
Quelqu’un sait comment trouver des NOBOs français, Allemagne, ou québécois sur le sentier?
Glossaire est difficile pour les non anglophones!
“Frenchman” -AKA “Sans Domicile Fixé” ou “Marcher et pleuré”
(au fait- The Trek rocks!)
Great job! The only one I question is section hiker. I consider myself a section hiker because I hike sections of the AT, at present I have almost completed New England. But there’s no way I will ever hiked the entire trail. Getting up there in years.
