Funny you should post this. A friend was asking me to help pull down some vines in her yard the other day. I said it would be fine as long as the vine had leaves that were not in groupings of 3! Although it's not good to pick it, this is a very nice shot!
It's good to actually see it, as my son has come back from his Grandparents a couple of times with poison ivy, and I'm paranoid about it, to the point I won't let him touch any leaf lol.....your shot will help......which is beautiful btw :-)
