Culver Academy had a summer camp that offered pilot training when I was a kid.
Their site is screwed up enough that I can't tell for sure if they still do,
but the program is mentioned in this old article
http://www.culver.org/news/publicati...non/May_03.htm
(look for "From Fleet Field")
and in this one
http://www.petersons.com/summerop/specnote.html
(look for "Culver Summer Camps/Culver Summer Aviation Program")

'seems like a place that specializes in flight training for 13-16 year olds
would be a good place to start.

(No, I didn't go to Culver. I was busy with music and cycling camps back
then. I wish I had though; it probably would have shaved some time off of
the 14 years I took to get my Private...)
