I have been to Phanom Rung and Muang Tam in June (but not in Buriram city itself, except for traveling through): http://christianpfc.blogspot.com/2014/0 ... g-tam.html

I wanted to go to Wat Kao Angkhan, but it was closed (near Phanom Rung and Muang Tam). We got a few km close by car, but then there was a police or army check point, no access for some days.

A friend told me about problems taking mocy over the border (a lot documentation, patience, time, and money required, and the border guards try to dissuade you from doing so). Poipet/Aranyaprathet border crossing in Sakeo province is not far.
