My great uncle died on the third charge up Missionary Ridge in Tennessee,

[On May 18, 1990, the 10th anniversary of the eruption, I stood on the ridge named for David Johnston. Next to me was Tom Brokaw of NBC News. Each of us had finished our respective live shots, and we stood in silence as shafts of sunlight beamed down between darkening clouds over the volcano.] You're lucky, ... I have to head out of here tonight, but you get to live near this mountain. There isn't a place on Earth like it.

I like the ridge line out there.

I realized mechanical engineering doesn't much lend itself to missionary work.

There are elements of family all through our unit, so if something happens to one person, we all help out,

We're together as a family, out in the open air, reliving history and sharing it with people, ... Doing this give all of us a different perspective.
