I like to always pack a small fan, kindle, and folding chair. Oh, and if we go somewhere with trees, then a sleeping hammock is a must.
My boy and his fellow scouts always bring a few decks of cards. Whenever there is downtime, one can always find a least one group of boys playing whatever card game is currently in vogue. Sometimes, a football or frisbee.
We have one asst. scoutmaster who is a whiz at cooking dutch oven desserts at least once during the week. Layer chocolate chip cookie dough, Oreo cookies, and brownie mix. Once done, it is topped with vanilla ice cream.....yum!
