The NCAA likes to minimize the expenses it has to pay out for the FCS playoffs where ever possible.
One such way they attempt this is to arrange as many matchups where they visiting team can be bussed in instead of flown.
Last I heard, they set the threshhold at 400 miles for determining if they pay for bus or plane. (if anyone has updated info on this, let me know).

Anyhow, I'm working on putting together a matrix showing all the potential playoff teams at this point, and which other potential teams are within bus distance.

Right now I'm working off of the following list of potential teams (which I pulled off of the bracketology thread). If anyone has any additions that they think I should include, let me know and I'll try and work them in.
