Eldo - The LDS Church has not left the Boys Scouts of America.  Each ward will continue to have a troop.  However, wards will no longer charter  a Venture Crew (for boys 14-16) or an Explorer Post (for boys 16-18).  Boys over 14 who are interested in progressing to Eagle will be chartered as members of the Scout Troop.  The change is more financial than programatic.
