(MOO) BL wanted to project the image of being a wilderness-savvy person. It's a pretty attractive "personality" type for a young 20-something dude, for sure. It's definitely trendy. Patagonia! REI! Shark-tooth necklaces! #ADVENTURE
It's the perfect persona to assume for someone who didn't (appear to) have much going on themselves (i.e. did not have a career, lived with their parents, did not participate in girlfriend's "van life" influencer attempt).
I also keep going back to the three very different climates BL has operated in, allegedly as an "outdoorsman." His hometown of New York (Long Island) and his supposed stints on the Appalachian Trail ; "barefoot" hiking (during summer?!) in the deserts and plains of the American West; and Carlton Reserve, swamps, Florida.
Skills for surviving (let alone thriving) in each of those climates are distinct. I find it very hard to believe that BL, or any 23-year old, was capable of truly understanding how to survive in all these disparate areas.
IMO, the "outdoorsman" persona is just that. He is just a regular dude.
