Just for context, the entire population of Wyoming is about half of the county where I live: 578,756 people in Wyoming. And that's in ~98,900 square miles - almost twice the size of England and over 3X the size of Scotland, for comparison.
Teton County has about 23,300 people in 4,216 square miles - so relatively populated and entirely due to the NP tourism infrastructure. Jackson has a population of 10,500 - so half of the people in the county live there.
Unlike Alaska, which is only about 85% land and the rest is water, Wyoming is 99% land - desolate, open, dry and windy.
I mention these facts to give perspective on how truly rural the area near Spread Creek is - the Moran Junction area has about 10-15 people living near it. Colter Bay is busy, because it's in the park. Many gas stations on the route through Wyoming have no attendants, especially at night, but I'd guess they have cameras these days.
Since people were asking about BL's "comfort zone," I'd say "not Merry Piglets and not downtown Moab." He liked going to that preserve in FL. There's no evidence that he was ever into gaming, but I believe he was into comics and book reading - solitary activities. He did a *lot* of drawing and had become notably proficient at linoleum stamp carving - a painstaking art requiring concentration and diligence. He did both small format and large format painting and had talent (not sure he still does - creativity requires a certain state of mind).
A guy like him would have a hard time establishing a relationship with any girl, it does not surprise me that they got together in high school. He was born in North Port, though, according to online searches. I do not think many women who are looking for men online will swipe on Brian (and everyone who does online dating wants real pictures of the person and will ghost a person if they try to meet and the person looks different than expected).
I don't see him as a guy who has "game." I do wonder what he's using for money and where he got it, if he is alive. I'm not sure he's alive. I'm not sure he can live without the conditions that gave him happiness and creativity. I can see him jumping off a cliff in some wilderness or national park...far from the crowds, though.
