i am currently a counselor @ a camp for kids and adults with pysical and devlopmental disabilites. many campers have ADHD or are bipolar (sometimes it is a secondary condition).
the staff @ our camp is very well trained to work with situations that arise when working with this population and the possible behavior problems that may arise (we all are trained in CPI and some have CPI cirtification) We also are taught how to relate to all types of poeple, no matter what is going on in their life.
i might say have him try a weekend camp first and see how that goes. you might also look @
http://www.kidscamps.com/ in the special needs camp section.
