I don’t understand why people like Facebook marketplace. It’s so transparently a way for them to just gather more shopping habits data on you, and it’s too easy for scammers to use. They act like having an account somehow makes it harder to scam.
I would much rather support the website run by a skeleton crew that has no unnecessary features than get a few bucks more on FB marketplace. If I’m selling something that I’ve used, it’s cause I want to get rid of it, anyway.
Here is a really good article about the topic. The gist is that typically in mountaineering, there’s not often an official definition of the “start point”, but the “end point” is back at the start, so people who die midway on the return journey don’t “count”. The “top” should be easy to define, but often, the top of a mountain is a large area, and you aren’t going to hike around looking for which part is just barely the highest. Also, some true summits are habitually avoided as sacred places to the locals.
