Basic routes
Jeuno - Sandy - Battalia Downs, Jugner Forest, La Theine Plateau, West Ronfaure, Sandy
Jeuno - Bastok - Rolanberry Fields, Passhow Marshlands, Konschtat Highlands, North Gustaberg, South Gustaberg.
Rolanberry Fields has links to both Batallia Downs and Saurowhatever Champagn (I can't spell!) so you can go Windy - Sandy without having to get off your chocobo, but you will be running close to time, especially if you don't know you way (there are a few short cuts that will help). Check
www.ffxi-atlas.com to get an idea of routes, and also getting maps is a real help, especially though Jugner Forest and the like.
