Teaching in Khon Kaen

Next month I'll go to Khon Kaen for two months and I'll join a local school to teach children English.

So far I never been in Isan, the north-east of Thailand. I'm very curious how it looks like and how the people are - the Isan People in Bangkok are very nice, kind and humble. I'm sure in Khon Kaen, they'll be no different :)
