Cycling home last night just past 8pm, close to Wat Si Saket/Mahosot hospital, a man on a motorbike tried to grab me (i didn't have a bag with me, so he wasn't after that) anyway I fell off my bike hard. smashing my face and various body parts on the road.....I got away with cuts, bruises and a broken tooth. There were two men on the motorbike, which fled the scene at speed. So as with anywhere Vientiane has it's share bad people.... As much as I love my bike (and need the exercise!) I recommend taking a tuk-tuk after dark.
