Final answer:
Without the context of the specific book or story, it's impossible to accurately answer where Travis took Gabby on a boat trip. The correct location could be any of the listed capes, but identifying the source material is necessary.
Step-by-step explanation:
The question appears to be regarding a storyline possibly from a novel or a narrative where a character named Travis takes another character, Gabby, on a trip on a boat with their friends. However, without the specific context of the book or story, it's not possible to provide an accurate answer to where Travis took Gabby. We would need to know the source material to answer whether they went to Cape Lookout, Cape Cod, Cape Coast, or Cape Town. For any literary questions, it is essential to have the text or at least the name of the work to reference the answer properly.
