Thanks for the video. I would say that my number one rule when out gathering greens for home consumption, is never ever gather, pick or eat anything within 20 yards of a street that has blacktop o n it. Reason being that the exhaust from the vehicles does contain poisons, like you mentioned, And if you are not on a dirt road, the exhaust spreads when it hits the blacktop. The dirt road rule I use is 10 yards. If you live in a rural area where the traffic is just the occasional car, you can make your adjustments, but remember blacktop is always a 20 yard rule for me.

Second if I am out hiking or just for a walk I always have a camera. Take a snapshot of the plant, if you are unfamiliar with it, and you can always google image search it. You can also take a small sample of the most notable part of the plant or the entire plant. I also always keep ziplocks with me just in case.

Third, I always smell it. I find that the most interesting of plants tend to smell different. Some of the more stinky plants tend to have a very specific highly medicinal use, I find. The more pleasant smelling plants also tend to have unique properties.

You are absolutely right never eat anything unless you are sure what it is.

Great vid and post, I think I might join you and do a hike and forage, while I am out take lots of pics and do a write up!
