Six Flags Over Texas (SFOT) Discussion Thread in Theme Parks, Roller Coasters, & Donkeys! Posted July 23, 2013 This is an incredibly sad event! I'm sorry for all people involved and hope they are coping well. Was just at Six Flags Fiesta Texas Today, and Iron Rattler was closed the entire day. I'm not sure how related it is to NTAG's tragedy but I'm sure it it had something to do with it.
