Step-by-step explanation:
The 'flower children' migrated to the epicenter due to their desire to live closer to nature, reject materialism, and express their discontent with mainstream society. Many of these individuals joined communes, such as The Farm in Tennessee, where they shared resources, practiced nonviolence, and embraced alternative beliefs and lifestyles. The counterculture movement of the 1960s, characterized by events like Woodstock, symbolized the cultural independence and freedom of the generation coming of age during that time.
