Mine was when Mom would take me, My Younger Brothers (2) and Sister (1) and our 4 Cousins on "Mini Vacations". It was a One Day Trip to a Museum, Zoo, or some other location like Arbuckle Wilderness, or Carlsbad Caverns.
We all piled in to our Station Wagon and ate sandwiches in the car on the way to wherever we were going. I STILL LOVE cold Hot Dogs wrapped in a slice of bread!!
