I went to a regular camp AND a CF camp when I was younger. I hated the regular camp because they didn't understand me at all and ignored my parents' instructions. I wasn't allowed to eat snacks when I wanted and I lost 6 lbs. in a week. If the regular camp is one you know specifically, go for it. Just make sure they understand what it is before he goes.
I hated the CF camp too, but for a different reason. The one I went to was not "camp for CF kids" but "CF CAMP" if you get my meaning. We didn't do anything but CF stuff. Even though I was not doing chest therapy at the time, I was required to at camp. I told them my home schedule was different and they didn't care. My mom ended up bringing me home early. So again with this, I'd only send him to a pulmonary camp if it's one you know doesn't suck. Haha.
Really, the "making friends with other CF kids" is important, I think. But I don't think camp is the best way to go about it, really? I mean if he wants to go to that one, it won't kill him. But regular camp would be good for him too. And as far as making CF friends, there are ways to do that where he won't be around them for a week straight. You can go to CF events, let him play with the other kids there. I was a CFF poster child when I was growing up and I went to all the CFF events, hung out with all the other CF kids. It was only for a day at a time and it was wicked fun. Pen pals are good too, but as you know, it's not nearly the same.
My basic advice would be: Unless he <b>really</b> wants to go to the pulmonary camp (and it has a really good reputation), send him to regular camp. And then go to CF events and let him make his CF friends there. <img src="i/expressions/face-icon-small-smile.gif" border="0">
