The Pledge of Allegiance:

How to Pledge Allegiance to the People:

Allegiance to the people is pledged in a manner similar to the pledge of allegiance "to the flag" except that the individual stands not at attention, but at ease and with her body turned directly away from the U.S. flag (or any national flag). While rendering this pledge, the individual should hold her right hand over her heart and calmly turn her head as needed in order to peacefully share eye contact with all those around her.

The perfect opportunity to pledge allegiance to the people is at the start of any sporting event, political convention, school day, or other similarly formal public gathering -- especially when the gathering is explicitly asked to recite the pledge of allegiance to the U.S. flag (or any national flag).
