Reminds me of the person I saw walking out of Smokey Mountain National PARK, carrying a wreath of a vine she was going to make a Christmas Wreath with, I guess. Then I noticed the few "leaves of three" (leave them be) dangling from the vines.

The Smokey Mountains will get the last word. That was Poison Ivy!! We tried to tell her, but she wouldn't believe us.

For our non-US friends, you are not supposed to pick anything in our national parks.
