Visit a bog and you can see fascinating bits like this lichen! And then you can eat it! "One quart of cold water, one tablespoon of salt, 12 ounces of pasta like elbow macaroni or spaghetti, three tablespoons of Extra Virgin olive oil, one cup of sliced lichens, one tablespoon of parsley, oregano, or Italian seasoning." You can take it from there. This is from urbansurvivalsite.com. Wouldn't want to miss that experience!
