Once again, you appear to be letting your assumed superiority cloud your judgement of other posters and their comments. I've not asked you to prove anything.
You posted what you felt Isaan's places of interest amounted to. I pointed out you'd missed quite a few.
As one of the more traveled persons, your words, you do appear to have missed a lot.
22 years I've been in Thsiland and I'm still visiting places I didn't know were there. Some I've found on the internet, others by word of mouth.
Some people are happy to be interested in and learn by others knowledge. Some, it seems, are not.
