Sunflowers

My brother and sister-in-law have been traveling out west. They went through Nebraska and then Colorado and said they saw huge fields of sunflowers. It was just gorgeous there. We are thinking they probably raise them for the sunflower seeds everyone loves to eat roasted and salted. What do you think? They went up quite high in the mountains too and the air got so thin they had a bit of a problem breathing while hiking since the air is thin of oxygen up there. You have to take it easy.
