Ok, so obviously those Man vs. Wild episodes tend to show the bizarre side of outdoor survival (really, a dead Yak's eyeball?), but after sifting through the ridiculous, there are a lot of good tips for finding food in the wild.
For one, I had always heard about getting water from a cactus, but had no idea what kind of cactus to look for, would it come gushing from the center, etc. His video showed what kind to look for, how to get at it, etc. Obviously, that option is if you are in survival mode. If you go camping in the desert, you should know to bring water.
But getting back to the original intent of this thread: do any of you here have alternative methods for finding food on the trail? Do you supplement the food you carry with food you can find to save weight or is this just a big, flat out no-no for the LNT types? Not to mention the added danger of not bringing enough food by depending on the trail to provide nourishment.
Just wondering what kinds of tips you might have.
