FAIRLEA, W.Va. -- Two hundred boxes of speakers, 30 electrical generators, 100 tractor trailers, 200 LED tiles making six massive video screens, 27 versions of the same blueprint and 550 people making it all go.
Putting on a concert in the middle of a field in Greenbrier County is a big undertaking.
"When I got here, basically the only thing here was a two-inch water spigot," said Gary Bowman, who is producing the Kenny Chesney and Aerosmith concerts in conjunction with the Greenbrier Classic PGA golf tournament this weekend.
Bowman has been planning for this weekend full-time for the past 10 months. In his office are detailed blueprints of the State Fairgrounds in Fairlea, where the concerts will be held.
Those drawings have transformed, from one iteration to the next, slowly becoming more complex until they morphed into the 27th and, hopefully, final version that hangs on the wall of Bowman's trailer.
Without all that planning, a lot can go wrong.
Jeff Bryant, The Greenbrier resort's director of entertainment, said they're expecting about 25,000 people for the concerts on both Thursday and Saturday. That would make the State Fairgrounds, for two days, the sixth-largest city in West Virginia, just behind Wheeling.
Those people won't just be descending on an empty field.
They'll find a stage, 60 feet by 80 feet, with 40-foot wings, flanked by huge walls of speakers.
There are also three islands of speakers set up in the middle of the field so the music sounds just as good in back as in front.
There are 20 trailers full of portable toilets. There are 11 concession stands and 200 trashcans.
All for two days, a few hours of music.
If that wasn't enough to set up, Bowman's team has to redo it all on Friday, between the two concerts.
Chesney and Aerosmith have different requirements in their contracts, not only for their trailers and their catering, but for their lighting, sound systems and the stage itself.
The thrust, the section of the stage that extends out into the audience, has to be completely rebuilt between shows because Chesney and Aerosmith prefer different shapes.
And every time a change is made to the stage, no matter how small, it has to be run by a structural engineer who ensures that the changes are sound and don't compromise safety.
