The last time my husband and I did a cross country ride I was able to turn our blog into a book. It came out awesome. I did use a different blog site though. Is there some way I would be able to turn my cycleblaze.com blog into a book?

It would depend on your publishing software, I imagine. When we post in our journals we write each post in a word processing document (in my case, Google Docs) or in an email (Bruce) to self. Then it's a quick cut-and-paste onto the journal. If you are planning to make your journal into a book afterwards, this is one way to get your text into an easily transferrable form.

I'm doubtful there's a way to just  cut-and-paste an entire journal other than doing the text, one post at a time, then adding photos and maps after that. A bunch of work, for sure.

You aren't saying what blog site you were working from before so it's hard to know if was a Wordpress or the like, or from CGOAB. But in any case, I wish you luck and hope you're able to have a great trip, a great journal, AND a great book!
