Unsung Heroes

One of the wonders of Riga, is the manner in which it is kept clean, every morning there "they" are cleaning the streets and pavements outside the various apartments and building. They sweep up every piece of litter ( of which there is little), leaves and anything else which has dared to descend during the previous day/evening.

So to these unsung heroes of Riga - I say thank you, you make a real difference - but I have one question when they have finished cleaning their alloted area - what do they do ? and where do othey go ?
