Probably Lymestone, a manufactured product. Probably a poor but cheaper choice - you know, like typical Trump knockoffs.

Yes. Maybe slightly fewer grammatical irregularities than usual? I could see this being one of the few things he cares about and thinks he knows more about than his usual nothing, that could explain it being 2/10 on coherence instead of 0/10. In any event, it looks like a damn parking lot now.
