"word of mouth to keep them alive"; vv', it's essential. All of the old ways learned, were received orally. Some words, concepts [like my visioned name spoken in Tsalagi], required waiting for a year or more before being called it by name. Several trips to Birdtown near Qualla [NC], which I was more than glad to make for many reasons. Having access to those who knew out there, in OK, and DC. Grateful to have it.
Just witnessing the fact - yes, there are many traditionals. Have been to stompdances that numbered yunwiya a hundred over, common in good weather.
