I showed my father this site and he started reading it. I wasn't sure what he would think but suddenly he's bought three of the books and intends to try this himself, so we got some good organic milk, butter, and eggs. We won't be going to a grocery store that's worth anything until Friday, though. (Funny how Kroger was my go-to place for fancy vegan foods, and it's now my best regular option for Primal foods.) I cooked some stuff in butter and I haven't had ill effects, so it looks like this transition will be fairly smooth. Can't eat meats yet, though, since what we have is crappy processed stuff with sugar in it.
