I don't think Cub Scouts is bad. It is a different program than Body Scouts, and that is good, because it's designed for younger boys.
I think alot of Weblos don't get the message, they think that Boy Scouting is just going to be more Cub Scouting. Plus, there are some that are really into Cub Scouting, but don't want to go camping.
Then there is another big group that is so into sports, that they just don't want to devote any time to Boy Scouts.
I guess better communication between the troop and pack would help somewhat, but, I feel alot of the attrition is due to the way the world works these days, and 100% of all Weblos are never going to go into Boy Scouts no matter what we do.
