JimCA recomended me ( http://board.gt-rider.com/topic.asp?TOPIC_ID=969 ) to take the road along the Mekong river from Kratcheh to Kampong Cham. I did it and had lots of fun. Here are a few pictures from the day that might motivate you to take the same road too. The road 72 nicely marked out on my GPS as one of the major roads (thick red line). The road also starts out really nice and easy. Plenty of people along the road that come and look at the "alien" when you stop. A lighthouse on the way. Marked out as LITE on the GPS shot above. A nice villa with view over the rice fields and the Mekong river. Some bridges are a bit basic so it takes a second to think about if it will manage my around 250kg. Local fishermen One of the main connecting roads. I was fooled to take it because it looked much better than the 72 at the intersection. Interesting problems always arise in Cambodia. Here is the solution. The last part of highway 72 close to Kampong Cham approximately at black arrow in GPS shot.
