Here's an updated list of "old school" ski areas. Remember it's not meant to be a comprehensive list, but just a collection of places mentioned by Divas in this thread. Go check one out in your region to see if you find a low key vibe, family friendly atmosphere, and less worry about lift lines for lower cost lift tickets. Don't expect high speed lifts though. Can be good places to learn for children and adults.
