I'm in my second semester of Lakhota at IU and we're using the Lessons.
The dictionary is really incomplete, so we have also been using the
Buechel Lakota Dictionary which can be purchased at Sinte Gleska on
Rosebud.
We've found the lessons to be pretty good...amazingly enough, we are
plugging away and having lots of fun!
Good luck, Kim...see you soon,
Paula
