Can you imagine a dentist buying other people's leftover Halloween candy? See how one dentist began a movement to buy back leftover Halloween treats to benefit our troops.

Here's what it's all about, according to a story by Allison Aubrey of npr.org:

"Check out the Halloween Candy Buyback program, which was founded by dentist Chris Kammer in Wisconsin. Kammer's office offers $1 a pound to buy back candy collected by the young trick-or-treaters in his practice.

This year, more than 2,500 dentists and orthodontists have signed up to participate. (There's a zip code locator, if you want to find a dentist near you.) By comparison, about 300 dentists participated in 2007, the first year the program expanded nationally.

And where does all this candy end up? It's shipped to U.S. troops overseas, as part of Operation Gratitude care packages."
