A few more cents to throw into the bucket...
I am a new adult leader and I wear my knots. I guess I fall into the category of a person that loves scouting and likes to remember all of the past times and likes to show the boys what they should strive for....
but one more factor...
I am trying to encourage my Pack leaders to be more aware of knots and the requirements that are needed to earn these knots. That is probably the best part of the knots... it sets tangible goals (measurable goals) for the adult leader. Advancement levels, training programs, Pow-Wows, Roundtables, etc. These things are invaluable to the scouting leader and a lot of people (like me... especially me) need things set down for me as a roadmap...
