Actually, the City of Casa Grande was named after the ruins, not the other way around. You can read about it here,
Fondest memory: Buying my first house here 3 years ago.
Favorite thing: Casa Grande is a fairly small town. Though it is growing very fast. We have all the accomidations, hotels, restaurants, grocery stores, department stores and golf courses. The small town attmosrhere is one of a kind. Locals are friendly.
