Flown in from Australia and need a carpool

My girlfriend and I have flown into town from Australia and decided to head to an LSU game. We booked game tickets for the Auburn game months ago and a return ticket to Baton Rouge on a greyhound on the day, very excited.

The start time for the game wasn't listed when we got the greyhound tickets, but my limited understanding of college games was that the games were in the afternoon - so we booked a greyhound back to NOLA at 7.50 pm.

We've just realised the game won't finish until 10.30 ish pm. All of the bus services that would help (like Baton Rouge Blitz) are sold out. Weve been searching desperately for a way to get back to NOLA after the game, is there a carpool service or any other site that has a good resource we can use?

Short of that .... is anyone heading to the game and wants to carpool? We are desperate here and are more than happy to pay for gas/beer (if LSU fans are anything like Aussies, beer is an official currency).

Please help!
