UPDATE: We have FOUND 'Cherry Cola'!  We were able to speak with her and she has a story to tell. Check out the interview here.

The Foo Fighters did not disappoint the city of Casper. Dave Grohl has a gift with how he interacts with the audience. A show is more about delivering an experience than just playing music for Grohl. You can tell by how he interacts with fans. That is what makes the Foo Fighters so epic. How they vibe with the crowd. Now all around town, we are talking about a woman nicknamed "Cherry Cola."

She was an older woman in the crowd rocking out to the Foos. Grohl tried to ask the woman her name, but as it is loud and rockers are deaf, he couldn't hear her. The nickname was born, when Dave said, I'll call you Cherry Cola.

Throughout the night, Grohl or others in the band would dedicate songs to her, but I think there was something most missed, and we want to know the rest of the story.

During one moment while Cherry Cola was on the massive diamond-shaped jumbotron, she was clutching something in her hand. At first, I thought it was a locket, but after another look, it was some military dog tags. While she was rocking out to "These Days," she kissed those dog tags as she held them.

One of these days, your heart will stop and play it's final beat

One of these days, the clocks will stop and time won't mean a thing.

There is more to this story somewhere. What is the meaning of the tags? We would love to hear about it.
