DON’T DO #34!!! EVER! Learn to use a map and compass instead. Otherwise, you will still be lost, and even the biodegradable tape still takes over 50 years to begin to breakdown- NO, just NO! Don’t do #6 in National Forests or on protected lands because it is illegal. I’ve done this as a project before, and it didn’t go as well as intended. Other than those 2, as an Outdoor Educator and Wilderness Guide, I don’t have too many issues with the rest of these.
