Iowa ghost hunter

From The Des Moines Register:

Pat Olson is a level-headed, feet-on-the-ground, middle-America kind of guy. He's a staff sergeant in the Air National Guard. He lives in West Des Moines. I run into some kooky people. It goes with the job. Olson, 41, is not a kooky person. He couldn't even play one on television. Sitting in the deli at Hy-Vee on Fleur Drive, decked out in his camouflage fatigues, he seems as dependable as a flag decal. You'd never figure him for someone who's obsessed with ghosts. Olson doesn't just believe in ghosts. He chases them, hangs with them, studies them, writes about them.
