Yep, that's the way to do it. I used to make a lot of my own stuff, pick up things that people threw away, go to yard sales and second hand stores which...anything to get me out into the outdoors. Now, well I have some pretty good gear and equipment, but I still never waste anything and treat everything as if it's irreplaceable. It's a good habit I think.
If you try hard enough you'll be able to work out a few ways to fish and hunt, snare and trap...it just takes some research, imagination and effort.
Good luck.
Thank you for the advice.
