We used to do roadies from Vientiane to danang leave at first light drive to lao bao on a busted ass road arrive on the Viet side after clearing customs then stay the night there. The viets aren't to bad to but same problem , leave it until the morning .we used to do those road trips all the time and safety was always 100% in my mind it was probably a bit risky putting my family at risk of harm.but we done it. And had fun .
