The Cubs in Shining Armor theme revolves around the ideas of honor and service. So organize a summer service project. Knights went on quests, so you could have some sort of fun “quest scavenger hunt”.
Here is what the current program helps say about this theme:
A Scout knows good manners make it easier for people to get along together. The word “courteous” is an old English word that comes from the time of knights. Many associate chivalry and graciousness with a knight in shining armor because of their code of conduct. The knight’s code of conduct extols these virtues, ensuring that a Cub Scout in shining armor will exhibit courtesy to all.
