Pack 136 is divided into groups called Dens for each of the Scout Ranks listed below.  Cub Scout dens are small age-based groups. The Den youth members make up a larger group called a Cub Scout Pack, which includes all family members.   Cub Scouts progress through ranks based on their school grade, and Scouts do not need to have earned a previous rank to start working on or receive their current rank. Cub Scout Pack and dens should be without stress over requirements, as the Cub Scouting motto is: "Do Your Best".
