Could you clarify to me the difference between using prepositions
in in such sentences (they are taken from some website, so they might be incorrect):
I arrived at Chicago on Monday. I've never been in Denver before.
Thank you for your help!
Found this question. Is the explanation from it by Colin Fine applicable in my case?
Both are equally correct, and have nearly the same meaning. In would mean physically within the bounds of the park, while at is slightly less precise, because she might be inside the park, or perhaps just outside the gates.
