RE: backpack fire extinguisher
I have one, and as far as it being a back pack? It is very uncomfortable on your back. If you can run a 50 yard dash with it on your back, you deserve to be in the MetRx worlds strongest man competition. I usually keep it in the truck and I just lift the trailer hitch off over the ball just in case I need to haul butt to extinguish a fire. Just my .02. Alex.
