Having been left to fend for ourselves in more than one place many a time I tend to read and learn and practice such things and look at each task as ......if it must be done...... where could murphy show up and when and have a "what if" alternative source of action if at all possible "before" it became an issue that stopped, diverted, maimed or killed.
I hated suprises.......:o)
Stay Safe !
Lucky for us, we never had to walk up the gangplank of a ship (like the Marines) with everything for our world for the next year on our backs! One trip, one load, that's it!
You should see Marines boarding a ship for a deployment. It reminds you of ants carrying stuff 3X their size. Ya gotta respect those jarheads! So they get one weapon each, and that's it. But they still do a LOT with that one weapon!
(I loved seeing the Marines embarking on ships with their seabag, their pack, their weapon, small bags clipped everywhere, and on top of it all, 9 feet in the air, a GUITAR.)
