Part of what everyone knows is just Rancho Cucamonga but residents feel needs to be separate. The Northwest part of Rancho where there are so many richy houses with 5 bedrooms, 3 1/2 bathrooms, and 30 square feet of backyard for your little yippie purse dwelling dog. A wonderful place to live if your dad is a Lawyer and your mom is a Doctor.
-Hey, you from the 909?
-Oooohh, you're from Ranch then, right?
-Alta Loma, Etiwanda, and Rancho are all the same and you know it!
