I have a question, you say “in the park” or “at the park” ? and why? “She is running in the park” or “she is running at the park”

In this case you can use in/at indifferently, both sentences are correct and have the same meaning.

Well, both are correct. but there´s a difference between them. In the park = within the park. Example -> I'm running in the park. At the park = park is conceived as a point in space -> Example. There's a concert at the park.

hi

I have the same question, but I consider that if we say the park's name, we should use "at", for instance: "at Central Park", because this is more specific.
