What is a Cracker Barrel at a cub scout camp?

A "cracker barrel" is an informal evening social event at which light snack fare is typically provided. Imagine the stereotypical image of a few folks gathered around or playing checkers on a barrel of crackers at an old-time country store.

At some events, e.g., a camp-o-ree, a cracker barrel may also offer an opportunity to disseminate plans or updates from the staff to scout leaders for the following day.
