Uncle Keith's Moon

My Dad often retells a story that took place about a year before I was born. At the time he, my mother, Grandparents and Uncle Keith were driving to Red Deer, Alberta (I believe) to see my Great-grandmother (lovely lady). My Grandparents and Uncle Keith were in my Dad's brown 1970 Cutlass coupe while my parents were driving Dad's turquoise 1970 Cutlass coupe, as they approached the narrow windy section of highway past Golden, BC they encountered a slow moving RV. Unwilling to wait for a straighter passing section they found the nearest clear section to safely pass and went around the RV in the opposite lane and the shoulder. As they pulled around to pass Keith (known as Keefer) mooned the elderly RV occupants. Delighting in his full moon rising, Keefer did not brace himself for the lane reentry that followed when the car was by the RV and fell bare rear in the air.
