No I can assure the awarding of ASM to the den leader is not a "ploy". My husband is VERY involved in Scouting at a pack and district level. The other ASM at this troop is also a leader in our Cub pack who happens to value what my husband does for the boys.
We have seen the other program in action as the Troop meets the same night as our pack. Total lack of organization, boys running around wild annoying the Cub Scouts, foul language, disrespect for fellow Boy Scouts, bullying...not something most of us want our boys to be a part of.
We have let the boys make their own decisions. They went on a campout with the other Troop and had a fantastic time....the older Scouts really went out of their way to make the Webelos feel welcome and to teach them Scout skills. There has been no lots of advancement talk...we have just seen first hand that this other troop is way more active and does more of the activities our boys would like to be involved in.
