After the epic North American Road trip in 2017, the Family continued to use the blog as a space for contemplation and sharing. The name Ola y Chau was given to Ola and Diala in Argentina in 2009 at the artist residency in Zona Imaginaria in Buenos Aires. Hello and Goodbye spent a total of two months in Argentina, after Buenos Aires they went north to Cordoba then on a road trip to Salta and Jujuy. Perhaps, that was when their wanderlust was ignited.
