On the fishing end, using pill baggies you can get at Walmart, you can bag up sinkers, small hooks, a spoon and 2 flies. I'd hope to use worms I'd find in a true survival situation, but in case I'm unable to or it's too cold, I have alternate ways to fish. The black things hanging out are the ends of the zipties you'll see next.
