"Has anyone heard of a group commited to filling the void that the Girl scouts left?"
Some Girl Scout leaders have become alarmed by the organizations leftward leanings and have decided to do something about it. In 1995, Patti Garibay, a former Girl Scout troop leader, founded the Cincinnati, Ohio-based American Heritage Girls (AHG), which now has troops in 32 states.
I just saw their web site. There are only two troops in Illinois. I expect to see that grow.
