The Roma come to the city in very inovative "vehicles" such as tractor or lawn mower engines used to power a small cart. They also have carts powered by bike and of course horses or mules.
Children are sent to stand in the middle of busy intersections and beg from cars at stop lights. You see many rooting through the garbage containers looking for some edible scraps. They come to open air restaurants and apartment doors asking for 50 cents or some bread and fruit.
It is heartbreaking. And the worst part is, there doesn't seem to be a simple or quick way to end this cycle.
