Hey, i just bumped into Routes at this site:
Its a plugin, where you can use google maps with your wordpress. Plugin destinations (Either through town search or by manually plotting destinations on the map)
Then the map can draw a line between your waypoints!
Perfect for traveling!! D
It works like a charm when using the plugin, inside the create post.
But when it comes to showing the output, i can't make it work. You have to edit your template file to get it work, and i can't get it to work :(
