Country jam is a large-scale production and from the lighting, to maintenance to security it takes so much work to make it happen.

In fact, while the performers job lasts just one day, those working behind the scenes say they've been preparing for months.

Craig Ahneman may not be a country star, but he's lighting up the main event.

"The stage lighting is gonna be the main focus for the show and they'll be a lot of really neat effects going on throughout all the show, but as far as out here, as long as you can see as you're walking to the porta-johns then I'm doing my job I guess.

Ahneman is Country Jam's site electrician. It's his job is to keep everything powered up and it's not an easy one.

"All the electricity, all the lights and it takes all of two, three weeks to get down here," he said.

His day started early, 2:30 this morning and he's been working ever since. But he's not the only one, over in the beer tent volunteers are busy prepping for all those thirsty fans.

"The beer is basically already iced, at that point the people start coming and we just serve the beer, to keep it going we have to restock the supply of beer as it runs out," volunteer Roger Dahl said.

And with so many fans, Dahl says it's a challenge to keep the cold brew stocked.

"You just keep running, you don't have time to stop and think," Dahl said.

Site security is also a must, and they too are putting in a lot of hours to make this day a success.

"A big part of our job is to get communication set up, get security set up and get law enforcement set up, we've been down here for three days, we've probably got about 40 hours in already," Michael Peterson, a lieutenant with the Eau Claire County Sheriffs Department said.
