I find myself at the counter, paying for fuel, still wearing my Mustang or EAM inflatable life jacket, because I have forgotten I was wearing it when I got out of the plane.
In addition to the feeling of security knowing I have it on going out the door if something happens, I also like the idea that it could be an improvised "airbag" should a rough forced land landing be immanent.
I have my life jackets set up with a few "extras" tucked inside (all tied to a line). Flashlight, Red LED wristband, emergency fire starter, and a well protected wire wood saw. I once had a friend survive the crash, and get to shore, to sped a night with nothing, because his emergency kit sank with the plane. So I take a minimum with me.
