In Thailand I only visited Bagkok so far, but for many times, I visited Bangkok when I was in the 20's, and 30's, and now I m in my 40's, some times I return bored, most of the times I m attracted by something.
I think Thailand has many attractions that are suitable for all of us, at any age and whatever is our interest, it is there and with many varities.
For Photographers I think it is heaven, many colors, our gears are resonably priced, and many beautiful faces or expressive faces or people....
