The whole night the bus went through Mesopotamia. In the morning we arrived at our destination in the northeastern corner of Argentina, the "land between the rivers". Mesopotámica, as it is called in Spanish, is the name for the region between the Rivers Paraná and Uruguay, which consists of the provinces Entre Ríos, Corrientes, and Misiones. Overnight the landscape had enormously changed and it was pretty obvious that we have arrived in a different climate zone. While Buenos Aires' climate is temperate, the area we ended up is hot and humid. The soil is wonderfully reddish brown and the surrounding flora is verdant and dense giving an air of adventure and paradise.
