As a s out leader I have to agree with teem8er. Bringing girls into the program was a good move for society as a whole. The troops work separately as the kids mature at different rates, however the girls are just as capable in the rough outdoors. Kindly remember this, in the early days of our founding, it wasn’t just the men who moved westward. Both the men and women of that time were looking for a tough individualism for a spouse.
It isn’t much different today. I will also say the girls will easily hold their own outdoors.
As a five-year Cubmaster I totally disagree. While dens and patrols could conceivably be kept separate, pack, troop, and council events would be coed. So would advertising for everything in "Scouts USA". Why is that a problem? Because the perception that scouting is for everyone destroys every notion that "this is what boys do". Do guys invite their wives to poker night? No, because it changes the dynamic and you'll never get more guys to join your game if they know there are women involved.
