Ditto on Mickey Mouse Hill! I was born at Castle AFB in 66, and lived in 'new base housing' across the street (Juniper Avenue) for a long time. I moved east in 1979, but have been back through atwater many times. I was just looking on Google Earth for Mickey Mouse Hill, only to find they scraped the whole thing away and put in a golf course :(.
As far as Mickey Mouse Hill, don't forget the 'swamp', which was an outfall for stormwater and was filled with pussy willow reeds. We used to catch frogs and all sorts of stuff in there. Rode my bike to death in that place!
