We just skyped the parents and realized two things.

1. They do not know how to hang up a Skype call. Therefore, we wait a few minutes and laugh as they wave goodbye thinking it'll hang up by itself then we turn off our side of the video and listen to their conversation.
2. This train ride is everything mom hates... small space, heat, and dirt. I'm sure they'll be having fun the next 12 hours :)
