The news early Monday that 50 people had been killed and over 200 injured during Jason Aldean's set at a country festival Sunday night in Las Vegas hit me really hard, as it did many of us.

Many of us have been to country music festival just like the Route 91 Harvest Fest this past weekend in Vegas. You go to these festivals to have some fun, let loose, and enjoy some great country acts.
