I went to Expo Prado with a teacher from one of my conversation classes and her friend. It was a great time.
Expo Prado is basically a large farm show or agriculatural exhibition in the Prado neighborhood of Montevideo. This year is the 104th Expo hosted by the Rural Association of Uruguay "where all sectors of the national economy are represented." And 530,000 visitors are expected to attend.
Besides all of the livestock displays (cows, pigs, goats, sheep, bunnies, hens, horses, etc.), there were also many businesses represented, from industrial tractor companies to cellphone service providers. A lot of corporations hired pretty girls in matching outfits to hand out advertising pamphlets to passerbys.
There were also public awarness booths (like for the transportation ministry or national army among many others) and artisinal stalls where I picked up a few presents and another silver ring for myself (I might have a slight ring-buying addiction. Somebody stop me!).
There were also lots of tasty food options. You could buy a hamburger from a little cart on the street or sit down for a full asado dinner. I personaly had a taco from the Mexican embassy's tent. Finally--some spiciness! The first time I've had anything with actual hot sauce since arriving in Uruguay.
I think my favorite part about Expo Prado was people watching. There were people from all classes and walks of life at the expo (and they were all drinking mate). There were gauchos from the interior, children in school uniforms, rich women in leather coats, farmhands in knee-high rubber boots, teenagers in skinny jeans, and grandpas in sweater vests. Everybody came out to take part in Uruguay's commercial and industrial success.
