I'm well aware of the paucity of buses in rural areas! My rural town used to have 4 bus routes that served the outlying estates, it now has one. And that's only from 9.15-5.45, none on Sundays/bank hols, and with a 90 minute gap in the afternoon when it becomes a school bus. And we have a (not at all useful) 3 buses a day to the villages and town north of here, and none at all to the towns on the coast. If you want to go to the nearest town, 7 miles away, you have to get a bus into the nearest city and back out again, so twice the distance.
There is a school bus though, because the town has outgrown the local comp and a lot of secondary age kids have to go to a village comp 5 miles up the road. Lots of kids get free school transport a bit further out in the sticks, because they don't have a school within 3 miles (2 miles for under 8s).
