The Little Debbie Million Smile Mission has reached the Inland Empire.

And boy, can we use them!

The Smile Missionaries have been tooling around the country in an Airstream trailer, connecting with Little Debbie fans, taking pictures of smiles to add to their mosaic and doling out free Little Debbie snack cakes.

We love free!

Oh…and you can win prizes, including Kodak cameras, printers, photo frames, Kodak Gallery gift cards and Little Debbie gift boxes. You could even win the grand prize — your very own 16-foot Airstream Sport trailer!

They’ve already made stops in Ontario and at Rancho Cucamonga’s Victoria Gardens.

Today (March 25) and Sunday (March 27), they’ll be in the Fan Zone at the Auto Club Speedway in Fontana.

On Monday (March 28), they’ll hit two Wal-Mart’s (12540 Foothill Blvd., Rancho Cucamonga and 4001 Hallmark Parkway, San Bernardino) and the Highland Food 4 Less (26529 Highland Ave.).
