Had an interesting experience today... I keep my auto-inflating PFD in my boat's rod box. Apparently it got a little wet in there with all the recent rains, and I came home to find the (previously locked) rod box lid sitting wide open and the PFD fully inflated sticking up out of the box. The part I want to warn folks about is this: The force of the inflating PFD actually *broke* the latch on the rod box!![/oooh: Fortunately, it wasn't on top of any of my rods, or I'm sure it would have broken them like toothpicks. So if you store your inflatable PFD in your boat, be careful where you put it - if it goes off prematurely, things could really get torn up!
