Bryan on Scouting is a Blog supported by the National BSA organization, aimed to provide useful information to adult scout leaders or “Scouters”, that is written by Bryan Wendell.
In his post for August 28, 2019, he shares 17 interesting, poignant or clever reasons behind pack, troop and crew numbers, and our Troop was mentioned as number 7.
It is very interesting to read not only the 17 examples cited by Bryan, but also the numerous other examples discussed in the comments as well.
