Yah, it seems like da place where a council could contribute is in those camp badges where a troop might not have da resources or a counselor. Stuff like shooting sports or lifesaving, eh? Outdoors badges that belong at camp. That's why council camps and volunteers exist - to provide services to units that they can't do on their own.
My feelin' is it should be a service to troops, though. That's what we council folks are supposed to do. When we make it a service to individual boys we're undermining the patrol, and the PLC, and the troop, and its adults.
Now if this is somethin' that a group of troops are askin' for because they don't have internal MBCs for some Eagle Required badges... OK, I guess. I'd rather have the council do a better job with counselor lists and active counselors that can really counsel boys in small groups, though, rather than runnin' another school class weekend.
