Passage
Wind-Wolf's educational setting has been not only a "secure" environment, but also very colorful, complicated, sensitive, and diverse. He has been with his mother at the ocean at daybreak when she made her prayers and gathered fresh seaweed from the rocks, he has sat with his uncles in a rowboat on the river while they fished with gill nets, and he has watched and listened to elders as they told creation stories and animal legends and sang songs around the campfires. He has watched the women make beaded jewelry and traditional native regalia. He has had many opportunities to watch his father, uncles, and ceremonial leaders using different kinds of songs while preparing for the sacred dances and rituals.
