A Czech Sprinkler System

I had to take this picture and post it. It just made me laugh. There are a lot of flowers around Prague and they are beautiful. The thing that is interesting to me is that they do not have a sprinkler system. There are trucks that come around with water and the driver gets out and basically hoses down the flowers. It doesn't seem very cost efficient but who knows, maybe it is. I have seen the watering of the flowers happen before but I have never seen it happen in a itsy bitsy bathing suit.
