I've visited EE a couple of times, such a beautiful community. I helped to build the living roof for their garden shed in 2005 and this short and positive experience redefined what I thought was possible in construction.

I know one of the instructors well from working with her elsewhere, I can give you her contact info if your sister hasn't already. I can also give you contact info for people who have done the program as students. From everything that I have heard about the program, I cannot think of anything negative.

Let me know if you want the contact infos and I'll send them your way.
