One of the things that make Montevideo a good place to visit is because its roads are very clean. Unfortunately, the dumpsters that keep all the trash are seen to be not pleasing to the eyes.This is why every time a President goes to Montevideo, the dumpsters of Rambla (and other streets where the convoy goes through) are gone. Weird, isn't it?
