have you considered that, for an experience like this, gifted might not be an important qualification? My DD is only 8, but ADORES her time at Girl Scout sleepaway camps. There are usually a variety of ages and interests, but it all takes place in that outdoor, relaxed setting...Our local YMCA has some regular sleepaway camps as well, so you might start there?
Now you have me thinking, since we LOVE summer camps so much...I'm going to start looking, heehee!
Oh, and who knows how many of those "troubled kids" are actually just not fitting in their environments? My DD has already been labeled as a "behavior problem" but we never have that at camp...some of those kids may be gifted too...
