A Question about the comic Sabrina the Teenage Witch

Or Seven Year Old daughter, MilliCal, wanted to ask this one, so I’m turning over the keyboard to her:
Why does Sabrina live in Greenndale now instead of Riverdale?

When Sabrina first appeared in 1962, she lived in Riverdale with the rest of the Archie gang. She was zapped back in time to her pre-teen years living in Greendale in the last episode of the Sabrina: The Teenage Witch cartoon (the early 70s version), as a lead-in to the new cartoon series Sabrina: The Animated Series, and the comic books followed suit at the time.
