Map of a bus route going up to Sadamine Pass/Bar-Be-Que Garden.
This timetable would be a heck of a lot more useful if I knew exactly what route the bus was taking.
This page has some interesting pics, may have useful info in the text. (No, I'm currently too lazy/sleepy to read the text. Maybe later.)
Must remember to take a look at where the Shoumaru lines listed on this link go.
Nngh, falling asleep. Must research later.
