An Army of Weed Eaters

Kuching has beautiful gardens everywhere and an army of men and women take care of them.  The one way roads are separated by gardens.  The bushes are sculptured by hand tools and weed eaters are the tool of choice for mowing down the grass. The grass is different than what we are use to.  Have not seen a lawn mower any where. There is a reason and I assume that they have found the weed eater to be more efficient and cheaper (the machine and labor).
