Swimming in the creek with my brothers and sisters in our undies. Then having to hide in the bushes when the Watkins man came by in his horse and buggy (remember Doc Adams from Gunsmoke).
Attending a one-room school with no indoor plumbing and a wood stove in winter. My mom's fried chocolate pies for lunch/dessert. Walking the 2 miles home from school.
Just a note -- I started grade school in the 40's.
Going to town on Saturdays and going to the movies with 50 cents for admission, a coke, candy, and a hotdog.
