Drove my scooter to the nearest border crossing showing on Google Map. 14 hour round trip, and deadly. Got to Laos border but nobody there to let me in, just hand scribbled sign that said "stop". Turns out entering Laos there wouldn't have done me any good anyway. The Vietnamese border agents explained that even if I could have gotten into Laos, they couldn't give me the kind of visa stamp I needed because I was at a 'national border' rather than an 'international border'. Looks like I'm in for a much longer trip next time (which has to be very soon), and I'm not up to driving it on my scooter.
