In Ramon "Tianguis" Perez's "Diario de un mojado", Perez identifies primarily as a "mojado" and a "macuiltianguense" (a person from San Pablo de Macuiltianguis, Oaxaca). The concept of community as elaborated in the diary incorporates macuiltianguenses on both sides of the border. This essay argues that Perez's transnational community must be understood within a framework that addresses both Mexican and U.S. national identities and nation-states. Although the main focus is "Diario de un mojado", the essay also includes a brief analysis of "Diary of a Guerrilla" as a way to place Perez's migration into context. In these texts, Perez does not undo national identities completely; rather, he dialogues with the dominant discourse of "mexicanidad" because he sees that it comes into conflict with his indigenous Zapotec identity, and he specifically rejects a U.S. national identity. The processes that Perez describes can be considered postnational, but one of the objectives of this essay is to question the "post" in postnational.
