Danville High, Walk to Kentucky 1913-1914

My grandmother, Alice Hickman O'Keefe walked from Danville Illinois to Mammoth Caves Kentucky in the winter of 1913-1914 with members of her high school class.  According to Google Maps it is a distance of 164 miles.  She was born in Danville in 1896 but raised her family in Massachusetts.  She died in 1986.
