For those geographically challenged. Glock is headquartered in Cobb County, GA (Smyrna) not terribly far from 6 Flags which is also in Cobb County.
Six Flags is in it to make money. They'll host anybody who pays. Even Disney, who has fought CCW laws in FL, had a "Welcome NRA members" sign when the national convention was in Orlando.
And yes, son owns a Glock.
