I will still be visiting Mapworld and buying appropriate touring maps for reference.
But as a fall back I've taken screenshots and downloaded cue-sheets for a bunch of possible routes from bikely.com. I also have some rail maps loaded.
The images are quite legible on the asus.
I also have PDFs of the NSW RTA bike maps. These will be... less useful. Hopefully I can get colour prints at work that will actually be readable.
