My son and SO are both headed off to summer camp soon (South Carolina and Florida, respectively). They have everything they need, but I'd like to get each of them something extra - like a splurge gift. Like, you don't need a fan, or an LED tent lantern, or a Thermacell, but they each serve a purpose and can make camping a lot more fun. Stuff like that. Curious as to this group's recommendations on "extras" that can make a week at camp more fun.
