Do Not Enter!

poison ivy do not enter sign

Ironic, ain't it? This lovely little vine growing up a tree next to a Do No Enter sign...

Yes, it IS poison ivy, ready to ruin the rest of your summer if you brush it, grab it, or use it for a decoration, as has been done.

This is in the northeast of the US, where poison ivy grows on country and suburban road, and in most cities as well.
