Hello!
My family and I go camping at least once a year if not more for about 5 days, and we sleep in tents and air matresses, and we think it's fine.
I bring a portable nebulizer so I can still do my nebs, and if possible I don't linger around the campfires, but I still roast marshmellows and stay by it when it gets cold! (I just usually have a bit more of a cough a few days after the campfire)
But, I enjoy camping, and I figure, there's so many things that people with CF could avoid, but then, that's missing part of life! <img src="i/expressions/face-icon-small-smile.gif" border="0">
I think it should be fine!
have fun!
