During April, 2003, Efrén Mezura Montes and Margarita Reyes Sierra visited Tulane University (in New Orleans, Louisiana) as part of a collaboration established through an NSF-CONACyT project with EVOCINV. Although they both had some work to do at Tulane, they found the time to enjoy the "big easy". New Orleans is perhaps the most european city of the USA, with a strong Spanish and French influence on its streets. Efrén and Margarita visited the main landmarks of New Orleans, such as Bourbon Streen, Riverwalk, the Superdome, Jackson Square, and the Natchez (a streamboat that navigates the Mississipi River).
