The Route 91 Harvest Festival is an annual country music festival held in Las Vegas, Nevada. It typically features a lineup of popular country artists and bands, attracting thousands of fans each year. The festival usually takes place over three days in late September or early October, offering a variety of food, drinks, and merchandise. The festival gained international attention in October 2017 due to a tragic mass shooting that occurred during the event. This incident led to increased discussions about safety at large gatherings and the impact of gun violence in the United States. The festival has since continued, honoring the memory of those affected.
