I hope this doesn't sound too frivolous, but I'm wondering if there is space for a couple decks of cards or some hand puzzles.  I thinking of something that would distract the occupants of the rafts while they wait for rescue.  Sitting around looking at each other under that canopy doesn't sound like a lot of fun.  I realize that these rafts are serious business, but I'm thinking of something that might help the occupants cope with anxiety and stress.  I confess that I am one of those weirdos that believes that survival is about mindset and attitude as well as gear.
