Fire firefighters have battled more than 20 large fires in Gatlinburg, Tennessee within the past 36 hours. More than 15,000 acres have been scorched, 14,000 people have been evacuated and at least 250 buildings have been damaged or destroyed.

Greg Ruff, who's father-in-law was evacuated while the house across the street burned, talked with Glenn on radio Wednesday about his family's harrowing experience.

"He's safe now, but he doesn't know if his house is gone. He's an artist. His home, after his wife passed away just a few years ago, turned into an art gallery that he lives in, out on Northern Creek. And, you know, all of his original art may be gone. All of his memories. All his kids' memories where they grew up may be gone," Mr. Ruff said.

In the midst of the tragedy, Mr. Ruff also offered a message of hope that came directly from his father-in-law.

"He just kind of . . . he paused and says, I'm grateful for my life. I've had a good life. I'm glad I'm alive. That stuff doesn't matter. And, you know, that's the kind of stuff we need in our world today. And people like you and your radio program, your TV program, Mercury One, and the people that work for you that are encouraging that type of stuff . . . I just want to tell you I appreciate it, and I appreciate what you're doing," Mr. Ruff said.

GLENN: Fire firefighters now are battling more than 20 large fires. The last 36 hours, more than 15,000 acres have been scorched, 14,000 people are -- have been evacuated from Gatlinburg, and at least 250 buildings have been damaged or destroyed, 100 of those are in Gatlinburg. People are in bad shape. And Mercury One wants to be there. We're going to -- well, I have some ideas on some things that I want to do, and right now, Mercury One is planning on being out there I think later this week. No one is being allowed in, except for the firefighters now.

But Mercury One is going to be on the scene soon, and we want to do something. And hopefully I'll have more on that tomorrow. But if you'd like to donate, you can go to mercuryone.org. Mercuryone.org.

Here's what is happening. The wildfires quickly grew on Monday night, due to the high winds. There were winds up to, what, 85 or 87 miles an hour. Those are hurricane force winds.

JEFFY: Absolutely.

GLENN: They caused trees to fall, into live power lines, which sparked new fires. The fire actually started -- they say that it was human-caused. We don't know what that means yet. This is, to me -- and I say this cautiously because it might have been somebody just flicking a cigarette out the window.

JEFFY: And they have arrested a couple people earlier this year on arson charges. So --

GLENN: Yeah, it may be arson. But if you look at what's happening over in Israel, Israel is getting pounded by fires set by terrorists. And this has been one thing that I have -- I thought of oh, I don't even know, maybe in 2001 or 2002.

I remember, Jeffy standing together in Tampa saying -- California. I mean, if I'm a terrorist, I come to California. I just set it on fire, and that's easy to do.

And that's what they're now doing in Israel. And I hope this isn't the condition in Gatlinburg.

We have -- we have Greg Ruff on the phone with us now from Gatlinburg. Greg, how are you, sir?

GREG: I'm doing fine. I'm doing great.

GLENN: Tell me what your situation is.

GREG: Well, our situation is my wife's father lives on Northern Creek, just outside of Gatlinburg. And he was -- he had surgery a little over a week ago for cancer and was at home, getting ready to go to bed. And had heard about the fires, but just was going to go to bed.

Well, his stepdaughter, one of -- my stepsister works for the park service. She called him and said -- knowing that he doesn't have a cell phone. He's an artist, and he kind of lives in his own world a little bit in that sense.

And said, no, you're not going to bed, you're going to leave. And so he started packing up. As they did, police were outside, clearing the street.

And he's still gathering things, and they're like saying, "You've got to go." And they looked, and the house just on the other side of his is up in flames. There's fire across the street of a one-lane road going into mountains is on fire.

And so he -- he -- you know, he has been evacuated. We have him now safely. You know, he has a little bit of memory issues. And we were really concerned about that.

But we have him. He's safe now. But he doesn't know if his house is gone. He's an artist. His home, after his wife passed away, just a few years ago, turned into an art gallery that he lives in, out on Northern Creek. And, you know, all of his original art may be gone. All of his memories. All his kids' memories where they grew up may be gone.

GLENN: Oh, my gosh.

How is your house? Where do you live?

GREG: I do not live there. I live in Nashville. And we went to go get him. Went in there. They let us get in and get him. And then so we have him. And we're trying to find a way to get back there.

His sister -- his daughter, I should say, his daughter-in-law who works with the park service, they thought they had lost their home. They found out they did not lose it.

Five people who work for the park services have confirmed they'll lose their home. And so they have to continue to work.

Last night, they had tornado warnings in Gatlinburg. They're like, "Please, no, it's raining. There's tornado warnings." And people were out -- my wife's sister-in-law's husband works for the city. And he was out at a blockade, you know, in -- uncovered in tornado warnings with rain pouring down all around and fires still burning. So it's been -- it's been very hectic to go through all that.

GLENN: Greg, our thoughts and prayers are with you and the family and everybody in Tennessee, wherever you are. And we wish you and your father-in-law, the best of luck. God bless.

CALLER: You know, can I share one thing?

GLENN: Sure.

CALLER: Because I hear you talk a lot about hope, and it's impacted me and my life. And so we -- my father-in-law goes through all this. We get him to our last night. And I'm doing some work because I need to do some work. And I'm listening. And he's downstairs with his daughter, and they're laughing and all that kind of stuff. I go down, and a few minutes later, and we're talking. He just kind of -- he paused and says, "I'm grateful for my life. I've had a good life. I'm glad I'm alive. That stuff doesn't matter."

And, you know, that's the kind of stuff we need in our world today. And people like you and your radio program, your TV program, Mercury One, and the people that work for you that are encouraging that type of stuff. And I just want to tell you I appreciate it, and I appreciate what you're doing.

GLENN: Thank you, Greg, I appreciate you telling us that. God bless. Thank you.
