Question: is there a six flags in houston tx

Answer: Yes, Six Flags AstroWorld was a seasonally operated theme park located on approximately 57 acres (23 ha) of land (later expanded to over 75 acres (30 ha)) between Kirby Drive and Fannin Avenue, directly south of Loop 610 in Houston, Texas. Opening on June 1, 1968, it was originally developed and constructed as part of the Astrodomain, the brainchild of local philanthropist and former Houston mayor Judge Roy Hofheinz, who intended it to complement The Astrodome.
