Was that a lawnmower?

I woke up this morning to a noise that seemed very familiar from my little suburban neighborhood back home: a lawnmower. Still half asleep, it almost comforted me. Until I realized that it could not have been a lawnmower, because there is very very very little grass in Spain. I mean, once you get out of the cities into more rural areas, especially up north, sure there's plenty of it. But if I were to look out my window right now, I don't think I'd see much...

[The noise, as it turns out, was the street cleaner]
