No, I haven't been stopped by "traffic police" in over two years. Those are the ones in blue shirts, btw.
They may have tried to stop me a few times alright.
Outside the capital it's almost never an issue ans a dollar fixes all, though the greedy ones may ask for $50 to start.
I reckon I could get a few expats up for this - a Khmer speaker makes things a lot easier and funny.
Depending on cash and commitments; I could slap something together for a few hundred bucks that may be fun to ride off road here. Next month will tell a lot.
Mines? No. Minefields are well marked. Not quite the hassle they were a decade ago.
