I didn't say I wouldn't eat, just that I wouldn't need a feast to see me trough 5 days awaiting rescue. I can SURVIVE on herbs, pine needles, worms, crickets, etc. for 5 days. Now if I could catch a fish with something other than my shirt, I would be LIVING not surviving wouldn't I?
I'm just saying a PSK is just that, nothing but a PSK. My fishing gear goes in my wilderness expedition kit, which I consequently don't take with me on planes.
