I had visited Argentina before in 2004-05 (during their summer) and had a chance to do so again recently. This time I didn’t have the opportunity to stay in Buenos Aires, beautiful city as it is, but was in the province of Córdoba for work. The people have always treated me well (even if someone did remark I speak like somebody from TV due to my accent :P), the food is wonderful and the landscapes of such a varied country are very beautiful.
Pictures are more eloquent than words, so some below (more here).
Rally has a huge tradition (and traction) in Córdoba as you can gather from the ads below (1, 2).
