"Tonight we're cooking for about 500," says Chef Scott Ostrander as he prepares a pot of alfredo.

In the truck next door, an assembly line puts together hoagies.

Workers say it's never easy but it's always rewarding.

"We're down to about 16 hour shifts, getting naps where you can and stuff like that but, just making sure that everything's operating. It takes a lot...It's a crazy business but, we love it," says Sam Clark with Big Sky Mobile Catering.

They're part of a team firefighters rely on to keep them safe and healthy to do their job.

"So they don't get here and have to spend half their time trying to take care of themselves," explains Information Officer Alan Hoffmeister.

Officials describe fire camp as a little city and this little city is not like others.

"A lot of times, this kind of an organization, with all its computers and its GIS systems and satellite communications are set up in a cow pasture and that becomes a challenge," says Hoffmeister.

Instead, folks with finance, communications and medical units all have a place to set up indoors and do their job or wait until they're needed.

"We're ready 24/7, if somebody calls, you go do whatever you have to," says the Medical Unit's Regina Sherman.

Even the availability of hot showers aren't taken for granted.

"If you're a firefighter, you have to have good, clean hygiene, especially feet, hands. I mean, your hold body but your feet are very important. If your feet are out, you're done," says Rocky Mountain Showers' Jim Anderson.

Some of the folks we talked to say their unit is like a little family, working together to support the firefighters and while it can get chaotic at times, it's all worth it.

"I enjoy it. There's a lot of challenges. It's just more or less a mind game. You either give up, go home or you work with it," says Gloria Bear with the Supply Unit.

Officials say, with the threat of windy weather Sunday, they're bracing for erratic fire behavior and say having an organized fire camp is more important than ever.
