They got to fill them!
They will be filled for Miami, Virginia Tech, Notre Dame, Kentucky, Florida State and Clemson. If we're ranked in the top 10 like we are now, they will also be filled for every other game, as well.
FWIW, when I parked at the Boy Scout lot (diagonally across from the baseball stadium) for the Friday night Duke game, a group of "UofL fans" dressed in black for the Blackout promotion got out of an SUV that had a UK vanity plate. As I walked from the lot, I passed another vehicle parked in that same lot also with a UK vanity plate. I probably wouldn't have noticed those two cars at all except for having read this thread!
I guess it could be something besides the obvious "UK basketball fans supporting UofL football" ... it could mean that UofL fans are stealing UK fans' cars in order to attend UofL football games!
