We have a phrase: "Besides, Seth had an afternoon guided fishing trip to run that began at 3 pm, during the hottest part of the day."
Explain please the grammar sentence construction, especially the first part. Is that split infinitive "Seth had ..... to run" and "had" is there a modal verb?
If I rephrase it to "Seth had to run an afternoon guided fishing trip that began at 3 pm" will it have the same meaning like original sentence? As I know split infinitive used when between participle "to" and "verb" is an adverb... correct me please if I'm not right
