Ridglea Hills has a stinking Walmart heh! The "Acres of suburbia" usually mean that it's a pain to walk to the store, not that the store doesn't exist.

I'd be surprised if there are many suburban areas that are more than 5/10 miles from "stores" for some value of store. Taking some central place of Ridglea gets me a 2 mile walk to Walmart. But there are no sidewalks.
