I live in SC and I have a cousin here with CF. People tend to develop allergies here in SC. I'm not sure exactly why, maybe it the warm weather, but anyways, my cousin has a really hard time with allergies. All of those particles in the air stick to all that thick mucus that CF people produce and cause even more mucus to produce. I love it here in SC but you might want to consider the allergies here that their effects on people with CF.
