It's an unusually bad wild fire season in the West, and for weeks people across the region have been breathing air thick with smoke.
"There's smoke from Canada, smoke from Idaho, smoke from California and Montana. There's smoke everywhere," says Greg Svelund, a spokesman for Oregon's Department of Environmental Quality.
A quick look at the Environmental Protection Agency's Air Now website shows unhealthy or hazardous air conditions all over the Pacific Northwest and into Northern California, Idaho and Montana.
"My lungs have been really sore. It's hard to breathe and it smells like we're in a campfire," says Tucker McClaran, who I found riding her bike in Portland, Ore. She's wearing what looks like a biker's face mask. "It's hot," she says. "It's chemically and it's gross."
