“We spent a lot of time doing nothing.. Watching the clouds go by, picking wild flowers, looking for arrowheads down by the creek, getting our feet wet. We groomed some horses, fed the chickens and fondly recalled the unstructured time of yesteryear; the best times of our lives.” R. Spencer and B. Murphy -Ranch Guestbook 2013
