Rural School District transport costs.

Knowing the already existing troubles for the school districts in the area, fuel cost increases will play havoc with spread out districts. One of consolidation's truism's is that economies of scale will provide greater opportunities for children. Does the data support this? One of the few studies examining this shows it does not work for rural districts because transport costs do not allow the economy of scale solution to the problem; transport costs eat up the supposed savings. To quote from this study:"As the number of children per school multiplied five-fold between 1930 and 1996, the per pupil transportation cost actually doubled". What does this mean for our districts in the time of near 100% fuel price increases, both for transport and heating? What will the solution be for this area, already hit by other problems?
