Just one small point: it's 18 miles from the beginning of Spread Creek dispersed camping area to Colter Bay. I took the geo coordinates from the Dyrt site that Gabby used. 43°46'20.4"N 110°29'03.9"W It's possible that it's a bit further. So this puzzles me. Did he really walk from the campground to Colter Bay? Or did he hitchhike? or did he take the van and just pretend to hitchhike (approaching several different people) and then trying to make sure they remembered that he's the guy traveling with the Youtuber gal - so that they'd remember him and help alibi him?
