Never seen this map/know who Taylor Politch is.
Why's it a problem if the locations are accurate? They are somewhat and then again not somewhat. Depends what you're looking for.
Idk how others do their maps. I only put things I'm sure of on my own map.
This map seems more like a personal diary type thing. 'oh I went here and seccys were there so idk.' 'ive heard lots about this being somewhere here but no idea actually.'
That's how I read a lot of those markers.
This is a good map for keeping the exploration element alive but I wouldn't use it as a basis for much credible information.
Wander often. Wonder always.
