Right. It is regional and out county extension office says to keep using what works in your area. In my area, this still works, and I had fecals run in February. As nice as Famancha is, it is not replacement for having an actual count from time to time.

That reminds me, I need to get another FAMACHA card. I think as long as you have been trained the first time, they will keep sending you replacement cards every few years.
