my friend just told me that the house and neighborhood used in the Syndicated years is located in Palo Alto California and the house and neighborhood used in the NBC years (you see it in the old intros and in the Mama learns to Drive episode, and others) was a fake neighborhood, and if you go down the road about a half mile, you'll see morning glory circle! The famous setup used in Bewitched!

The Bewitched House is located on a studio in Hollywood
Mamas Family house is NOT located in Palo Alto CA
Your thinking of the Dynasty House

And what proof do you have?
I live very very near Palo Alto and there is no such house
