  • Redding P.
    "Mountain House is good for very young children, but school age children find it boring as there is no downtown area or attractions, not even a grocery store or gas station. The weather is also very hot sunny and windy, so being outside can often be unpleasant for about half the year except for dawn and dusk in the summer. "
