Not only in Vientiane but throughout Lao, I travelled from Vientiane to Pakse and then to WatPhu, I saw there were a lot of rubbishes along the main roads, particularly PLASTIC BAGS, I want to say you can't not count them those plastic bags....terrible. To get rid of them you must burn them the PLASTIC BAGS. Those plastic bags lied aroung they made LAO like a TRASH COUNTRY.
