Jumped on the bike one early evening and head up to Phimai in Khorat.

Stayed in Khru Pom guesthouse which is about 20m in front of the temple just next to the 7-11. (it's a small town). 350b per night I think.
Unfortunately the temple isn't lit up at night so no night shots. There's a massage place around the corner (the GH owner will give you directions if you speak Thai) so an oil massage for 300b, no happy endings on offer.
There's actually a really nice bar on the otherside of the 7-11, but with shit service and shit food it's a waste of a nice set up.
