As I’ve started to travel several kilometers outside of the city of Siem Reap in the last few days, I noticed that many of the shops had a rack of rather disreputable looking bottles full of yellow-ish liquid.  Asked someone today what it was… gasoline!  While there are very familiar-looking gas stations in the city itself, gas can be had by 1- and 2-liter bottles as you go farther afield!
