So, I've heard "over yonder", and I've heard "as the crow flies", and I live in an area where neither of those phrases are uncommon to hear... But I don't believe I've ever heard them both put together like that.
"Over yonder" is a casual phrase that's used to indicate the general direction or location of a place or thing, usually accompanied by a finger pointing in a rough direction.
"As the crow flies" specifically refers to the shortest distance between two points, rather than travel distance. Like, "the distance between New York and Washington DC is 231 miles by road, or 204 miles, as the crow flies."
"Over yonder" already implies that we are referring to a straight line from A to B, so it would be redundant to add "as the crow flies" after it.
So like, are people really putting those two phrases together like that? If so, I must protest. /angryface
I find it difficult to defend the idea that Reddit is not a leftist echo chamber. I love Reddit, but it's not a place you go for open and honest discussions between people from both sides of the aisle. Even non-political subreddits will meet right-leaning and conservative ideas with hostility. You can browse the front page of Reddit every day and never see a single thing even remotely pro-Trump or pro-Republican. That's not a knock on Reddit. That's just the truth.
