Six Flags Discovery Kingdom has anchored itself in Vallejo since relocating from Redwood City in 1987 and rumors of the theme park sniffing around Fresno are unfounded, according to Vallejo city officials.

The Times-Herald received an email late Thursday from a citizen claiming that Six Flags is “eventually going to move out of its present location to Fresno” presumably because the park was dissatisfied with the alleged slow progress of Mare Island and the Solano County Fairgrounds’ 360 Project.
