I'm a cub leader, and so I tend to have a different perspective on this than many. At the Cub level, it's rare to get a long time leader with lots of bling, knots, etc. More of the long timers I meet tend to go the opposite direction - they shun knots, rarely wear WB beads, etc. A temporary patch - what's that? So, the new Cub leaders that I know pick up on that and don't bother either. In my 4 years with my son's pack, I am the only person to ever earn a knot out of probably 30 different leaders. As such, I get questions all the time from the boys - Hey, what's that on your uniform?
I'd love to have some around the block guy show up at the pack meeting with more bling than you could imagine. I imagine a lot of kids would love it!
