 Honorary Forest Ranger Betty White here lending a hand to my dear friend Smokey Bear because for 75 years he's only said, Only you can prevent wildfires. But there's a lot more to say. Like if you park your car on tall dry grass, the hot exhaust pipe can start a wildfire. So be careful out there. Go to SmokeyBear.com to learn more about wildfire prevention. Brought to you by the U.S. Forest Service, your state forester, and the Ad Council.
