When I read TWTM it felt like coming home. I had done a "box" curriculum (though heavy literature-based), but I wanted more flexibility, I wanted to go deeper in high school, and I wanted a 4-year cycle. My dd and I have heard SWB speak many times. She's a wonderful speaker - gracious and doesn't take herself too seriously. We like her so much, we drove 4 hours to hear her last summer - and I retired from hs'ing a few years ago.
