Fuel costs and non-conference schedules

I would love to see a guru on one of the major websites address whether or not high fuel prices has affected the non-conference schedules this season. Surely it has to, perhaps not so much on the crowded east coast, but in far-flung conferences like the MWC, WAC and SBC, their conference travel costs are already horrendous, and I would think they would schedule close to home during the non-conference portion as much as possible.
