Blissful... to answer your question about Girl Scouts... as a long-time leader... the answer is, yes, and no. Girl Scouting, unlike Boy Scouting, does not follow a standard progression in terms ot rank, so there are no benchmarks girls have to hit to progress to the next level, as they do in BSA. How outdoors-y the troop is, is almost entirely up to the individual leaders. As a girl gets older, she can also seek out outdoors experiences via the national GS/USA program (the old "wider ops" if you remember those). Girl Scouting is also something more of a girl-driven program than is BSA. If the majority of the girls in the troop want to do camping, hiking and backpacking, then if it's working the way it's supposed to, the troop will do those things - but if the girls are more oriented towards other activities, then the leader shouldn't force the girls to go out if they really don't want to. Another point is that many girls leave Girl Scouting by 5th or 6th grade - this is the time when any Scout troop will start getting out into the outdoors on a more serious basis (even most Cub troops don't do much serious outdoor stuff).
If you (or anyone on this board) has any interest in promoting outdoors activity for girls, I'd strongly recommend you locate your local council and figure out how you can get involved. Most GS leaders, it's true, do NOT tend to be experienced outdoorswomen, but would very much enjoy having strong, positive, outdoors-y role models for their girls. I know I would!
