URGENT! Need ride from Tucson, AZ to Fort Huachuca, AZ!!?

My son urgently needs a ride tomorrow night (Wed. 4/27/11) from the Tucson, AZ airport to Fort Huachuca, AZ (near Sierra Vista, AZ) just the one time one way. Money is a significant challenge so we are doing everything possible to get the cost down as low as we can.

This is a love story issue. He is going to see his wife graduate from Army Training (AIT). He didn't know he would need to go until today. He must be there and has all arrangements worked out except how to get from the airport to the base.

Is there anyone who is willing to drive him that might be going anyway? Maybe willing to drive for the gas money? Or you know of people who can help? Or perhaps you know of a service he can take that is $10 or under or as inexpensive as humanly possible?

Any help/advise you can provide will be much appreciated!!! Please respond as quick as you can as time is of the essence. Thank you all!!
