I'm currently writing a paper and I have a question about the usage of the expression "in the midst of". I wrote: "I hope to find out more about the challenges of rebuilding a city in the midst of a major industrial boom", but I realize now that I've rarely seen "in the midst of" associated with something positive. It's usually "in the midst of a crisis/war/breakup" or whatever. The dictionaries I've consulted don't mention any negative connotation to the expression, so I would love to have the input of native speakers/vocabulary experts.
Can something happen in the midst of something positive? And if not, what might be a better expression?
