"Hot. Very hot. It's probably 95 degrees and the sun is just beating down," said Angela Bachman, out for her first time at the outdoor concert.
But the hot weather isn't stopping Sandy Bronkhorst, a diehard Country fan.
"I’ve never missed a show. I've been to every show," she said.
That’s right, 17 years. But Bronkhorst knows all too well about the hot weather. She had a heat stroke a few years ago at Country USA.
"It was scary. All of a sudden, I didn't know where I was or what was going on and I was just very, very sick," she said.
Now she and other fans are taking precautions.
"The number one thing is know your limits and stay hydrated, with water and different sports drinks like Gatorade and PowerAde. That's the most important thing," said Lucas Rappert, a volunteer with the American Red Cross.
The Red Cross will be on hand all week, and organizers tell people to pay attention.
"We've learned nothing is unusual when it comes to weather for Country USA,” said Cher Liebhauser, organizer.
They'll let you bring in a sealed bottle of water, and make tents available for shade. They even opened up the gates a day early, so people could get their wristbands and avoid long lines in the sun.
"We are on what used to be an existing farm land. So we're out in the open so the breeze, as you can tell, cools you off more than if you were in the city," said Liebhauser.
The Red Cross said to wear cool clothing, and like any outdoor concert, if you're planning to drink, know your limits. Not just drinking alcohol, but water too.
"Just be aware of the heat and what you're dealing with, like at any event," said Liebhauser.
