Welcome To Rockville has been plagued by bad weather over the last couple days. Unexpected storms have forced organizers for the festival — which is located in Daytona Beach, FL — to cancel headlining sets by Guns N’ Roses and Korn, as well as performances from Bush, Shinedown, Rise Against, and more. (Megadeth, who were supposed to perform on Friday, also dropped out due to travel delays from Canada.)
