I'll remember Roger Yrurtia for two things. One: for having a last name so ridiculously intimidating that I won't even try to pronounce it. And, two: for his gorgeous sculpture called Canto al Trabajo ("Song to Work").
I can count on exactly one finger the number of times I've stood before a flower sculpture and thought to myself, "Now that is really fucking cool".
The most striking aspect of the northern barrios (Retiro, Recoleta, Palermo), especially in comparison with their less affluent southern counterparts, is the number of beautiful parks and green spaces. One of the most remarkable is the Carlos Thays Botanical Garden in Palermo.
