1 - Probably the best thing about the park is the roads. No pot holes, just long open roads. Some of them very curvy but lots of fun for driving. Unlike the drive back which was 5 hours to do the 180km back to Bangkok on Sunday night. It was a long weekend in Thailand and every damn car in the jams had Bangkok number plates. Reminds me of the M4 into London on a Sunday night.
2 - I love these water monitors. When I'm cycling, they are often in the bushes by the canals. When they see you, they scamper off. First you know is that it sounds like an elephant is running in the bushes next to you. They are harmless, but first glance at one in front of you always makes you think "crocodile"...
