less than one dollar! hehehe..Yes I did spend a lot of time at the back. Just watching the track behind. The funny thing is people actually walk on the tracks...crossing them. Children playing there..But the train moves slowly. Never felt it was dangerous. The vendor did hop on and of, selling their stuff. 3 hours can seem a long time, but it did not seem that long. There was something to look at all the time both inside and outside the train. I can recommend :)
