This has been my favorite find:

This is summer 1976 or 1977 - at the horse stables in Powder Springs, GA. My dad boarded our horse there - either Grey Boy or August Fog. My sisters would know. So that's Dad, Paige & myself in the bed of his truck. Guessing Paige is around 9. Love my Dads hair. (ha!)
This one is a classic.
