I was looking at one of Survivorman's fist season episode "Lost at Sea", which made me think of y'all!
If you haven't seen it, it's the episode that they used an inflatable raft that's stored in a hard case located on the deck of a yacht that is also attached to a depth gauge explosive to detach and inflate the raft in the event that the raft is on the yacht while it was sinking.
Ok Pops, so what's that got to do with flashlights?
Well the raft has a emergency survival kit in it, and when Les Stroud opened the kit, guess what?
Don't know? ... Don't wanna at least give it a guess?
Ok! You guys are NO fun!
The waterproof flashlight in the kit didn't flashlight! I mean light or didn't work!
So I guess the moral of that episode is too make sure you got your own waterproof flashlight on your person for a just incase type of thing if you're on a yacht! Les was SOL, cause he didn't have one on him!
