Cambodia February, Laos in March
 

Will be riding in Cambodia roughly 2/11-2/22, the Laos thru 3/15 or so....

I might be completely wrong, and im sure you have checked this already,

but a friend of mine travelled up vietnam and planned on going through Laos into thailand but he said at the Lao border they wouldnt let him bring his bike through due to new border control rules, so not sure if they would like you take your bike into Laos? maybe check up on it first.
