depicted as even having its own subway system. Next door to the Flintstone residence was Tombstone Manor, home to the Gruesomes, who were parodies of the Addams Family: Weirdly, Creepella, and their son, Goblin (a.k.a. Gobby), as well as a strange assortment of relatives and pets. Later spinoffs would introduce the Frankenstones, similar monster-themed neighbors of the Flintstones. Location Bedrock is the county seat of fictional Cobblestone County, and stated in the first-season episode "The Tycoon" to be 200 feet below sea level; presumably, the nearby town of Red Rock was located in Cobblestone County as well. However, no further information was ever given for any of these locations, besides being set in a prehistoric version of the United States. Near Bedrock lies Granitetown, given in one episode as the one-time childhood hometown of Barney Rubble and Fred's boss, Mr. Slate. Bedrock in one episode is shown as being a two-day drive from Rock Vegas, and in another episode, several hours' drive from Indianrockolis, which suggests that Bedrock might be located in what is today the Midwestern United States.

The season two episode "The Rock Vegas Caper" shows the Flintstones and the Rubbles, while driving to Rock Vegas, passing the Grand Canyon; being in prehistoric times, however, the "canyon" is depicted as little more than a small stream. Fred, however, notes it "might be a big thing someday." The season one episode "The Monster From The Tar Pit" shows Mr. Sandstone of the movie studio Miracle Pictures talking to one of his directors about staging his movie in a real town. When asked where, Sandstone walks to a flat earth globe, closes his eyes, points to an area of the map that appears to be in modern-day northern Iowa or southern Minnesota and chooses Bedrock. It has also been suggested that Bedrock is fairly close to the ocean or to the Great Lakes, as the city has a yacht club, plus the Flintstones and Rubbles have taken several
