Linking blog posts underneath other blogs

Hi! I am working on setting up my travel site, and I have 1 blog called Guides & Itineraries and then a Folder with blogs underneath it called Arizona, California, Utah. I've already put a few posts underneath my Guides & Itineraries blog, but I want to link some of those posts to go underneath the corresponding state blogs in my Folder, so that way they will show up underneath Guides & Itineraries or if someone is searching underneath a specific state in my top nav. Is there a way to do that, or did I set my site up incorrectly? 

If you still need help, there is a way to do this. Post a link to your site, let me take a look and I will get back to you.
