Some SSA chapters have had very successful, on-going youth programs.
Youth involvement is structured on a value-added, performance based
program.
http://www.texassoaring.org Youth Program (about 35 total involved Feb
2006, including a then 17-year old tow pilot)
http://www.harrishillsoaring.org/ Junior program (some good video
links in RAS a while back)

Add to that, the Greater Boston Soaring Club. So popular that there is a
waiting list for the youth program. See http://soargbsc.com - click on
"Junior Program".
