Car drive on a snowy day(1973)

This is a video of driving the "Aso Daikanbo" and "Yamanami Highway" on a snowy day in 1973.
In the 1970s, in Hita City, where our family lived, there were days when it snowed three or four days every year.
On a snowy day, our family went for a drive in Aso-Kuju in search of a snowy landscape and enjoyed the snow that had fallen.
