Day trip to Ayutthaya!
Went in search of the Chang factory, but with no luck! Apparently it is the other side of the town to where I was visiting!
However, I had a temple day and I visited Wat Phu Khao Thong - large stone temple, Wat Phra Non - reclining stone Buddha (Phra Budhasalyart), Wat Lokayasutha, Wat Maha That - temple that was destroyed and the Buddha statues were beheaded, this is where the head of a sandstone Buddha is inside a tree, Phra Si Sanphet Temple, and Phramongkhon Bophit Temple.

Returned back to Bangkok in the afternoon and waited for a night bus to Chiang Mai.
