The Horse Set

When my mother referred to someone as part of the horse set, she meant they were among the useless rich; people who had so much money, they could afford to spend all their  time riding horses.  I don't know anything about the people in these photos.  For all I know, they worked hard, had professions, and were generous with their money.  What I do know is that these photos were taken in southern California, probably from the twenties.
