  1. Great resource for all that roam the woods. Even if you are not allergic to it now, you can develop an allergy to it if you are overexposed. Also be careful even in the winter if cutting or handling wood- I cut into one of the vines that was attached to the dead tree (see the pics in the link in the article), and didn’t know it was poison ivy- and ended up with a reaction.


  2. Rating:

  3. This was a quick and easy reminder for any and everyone! This information is relevant for those who work out in the woods, but also anyone who does basic lawn care or gardening at home.


  4. Coming to NPS from a part of the US that doesn’t get poison ivy, it’s nice to have this much information available BEFORE I learn the hard way.
