That's correct. In my neck of the woods there are a number of existing Troops (5 in the immediate area), but none fall under our CO. Our CO does however have a cub scout pack.
While "linking" to my son's troop would have certainly been easier (and I think the CO would have supported it), the scouts there are overwhelmingly against having girls in the BSA in general, and most certainly against sharing meeting space. Rather than force it, I feel being non-linked gives these girls the best chance for success without having to worry about ruffling any feathers...Little extra work on my end, but I'm happy to add to that 1 hour a week
That being said, i think all units are eventually going to be co-ed, you just have to give everyone time to adjust...
