Hi welcome to greekchat,
I can see in a way where you are coming from. While I understand the importance of Arrowmont myself it can be hard to tell PNMs this during recruitment. In the past whenever we have talked about arrowmont as our philanthropy to them it does not seem as significant. So we have always gone with literacy as our "philanthropy" during recruitment.
Also, I think to understand the importance of the philanthropy you really have to understand the area in which it is located. This really demonstrates why it was so important at the time. Going to school in southwest VA and having seen a lot of these areas growing up you can see why it was so important to these areas that had nothing until Arrowmont was created. If you go there now, there is a whole strip and city area built up around Arrowmont. We always joke about how its the myrtle beach of the mountains.
Hope this helps a little.
