Riding around the city you get to see the most interesting things. One of the major side streets in Phnom Penh runs along this canal. See the blobs in the water? Garbage. See the water draining into the canal? Toilet effluent. Yep, this is an open sewer. Like many developing countries Cambodia is still struggling to find a way to remove what remains after human use. BTW, in Cambodian Sign Language one does not call streets by their names (since many don't read), but by landmarks, hence this is Street that Stinks.
