I had never heard of "hippotherapy" before I read this opinion. I suppose that even with my limited knowledge of Latin roots, I should have been able to figure out what it was before the third page of the opinion. But I didn't.
I know now, though. The clue being that it is not a type of physical therapy that involves putting the patient on a hippopotamus.
I also now know that California doesn't pay for it. Just regular old PT.
POSTSCRIPT - A reader with an ancient tongue notes that "hippo" is actually a Greek root, not Latin. My ignorance seems so much more justified!
