When I look at the generic maps, like the one on Saanendoah, they show that - in general - Texas is in the zone of "adequate selenium". The map we link to in 101 is more detailed, but I still am not sure how to interpret it. We have not yet used Bo/Se - as I have not seen signs of us needing it. But I bought some yesterday, anyway. Am I the only one in this part of Texas (Diane, Lynn, Vicki, etc -- all of you included) who does not regularly use Bo/Se? And if so can you tell me your experiences using it and not using it? And how you feel about the map differences? Thanks!
