Boulevard of Broken Backsides

I made the journey from Thailand to Cambodia the other day and Lonely Planet finally got something right. From the Thai border to the town of Siem Reap the road is utter hell. First its the start of the monsoon season and the road isn't really pavement, more dirt. So there are puddles and mud everywhere. Getting across the street is an adventure in Poipet, Cambodia (the border town) and its absolutely disgusting here. Huge dirty casinos litter the streets and I wanted nothing more than to leave...that was until we got on the road. I mentioned it was muddy and filled with huge puddles from the heavy rains but the road is also insanely bumpy, worse than anything I'd seen and I was on it for about 4 hours traveling to Siem Reap. It was miserable, but I had some nice company of a older German couple in my share taxi to enjoy the experience with. The guy, George, had traveled extensively all of the world when he was younger and had some great stories about some of the place in Northern Thailand when they were less developed. The roads up there weren't paved and the town of Pai, now a tourist hotspot, wasn't even on the map. Things have apparently changed. And I hope they do on the roads of Cambodia. Lonely Planet warns you about them but most of the things they say I have found to be exaggerations so I didn't believe them, but the road truly was the "boulevard of broken backsides"....they also claim that they get better from here, fingers crossed.
