Trip journals are trip specific blogs. That is a blog about a specific trip that I've taken. I have them ordered first item first which is backward from a typical blog because it makes it easier to read about the trip from start to finish. Granted that also makes it more difficult to read the latest news when I'm on vacation because the most recent entry (the last one) will be last. But, since most people don't actually get around to reading the Trip Journal until after I'm back I think that will be ok.

Also there's a ton of them missing, this article will explain why.
