A pick-up truck is driving around Illinois with a special message on the back.

Chad, who installed the lettering on this vehicle, shared a photo to a local Facebook group urging people to share the work he had just done.

He wasn't asking for people to applaud his work, or to receive any sorts of compliments. He wants to share this very important story.

A man with a pick-up truck is looking for his grandson's hero.

His grandson is in need of a new kidney. According to some of the comments on the Facebook posting, the grandson is 25-years-old, O+ blood type and his kidney is functioning at twelve percent.

If someone believes they are a match and would like to donate a kidney, they can call 815-992-9403.

I think this is just one of the sweetest things I have ever seen. Please share this story and maybe one day soon, I'll be able to report that the owner of the truck's grandson got a new kidney.
