This paper analyzes the nature of linguistic interactions between host communities and international tourists. The tourism-based context provides an excellent platform from which to describe the sociolinguistic influences that American tourists have had on Mexican communities. Specifically, the language use of local vendors in Puerto Peñasco/Rocky Point, Mexico, is described in terms of the various linguistic characteristics that constitute their particular dialect of English. Not only does this work emphasize the sociocultural foundation of language acquisition, it also illustrates the type of language that is learned in economically motivated situations. The results also emphasize how the growing ubiquity of (American) English in tourism contexts establishes distinct attitudes towards the United States and those who live there.
