Casting Crowns Giveaway

On a leap of faith that we would eventually be able to find six to eight friends to buy them from us, Sheila has bought ten tickets to the Casting Crowns concert at ACU Moody Gym on April 24. By buying ten, rather than four (for her, me, and our two older kids) we qualified for a group discount.

Since we've got some extra tickets, now, it occurs to me that I could use a couple of them to do some kind-of auction or contest. I'm thinking - at a minimum - we might just take bids and then give the money to World Vision, but I'd like to do something more creative.

Any ideas, anyone?
