Poison Ivy?

Quick! Is this an innocent flowering vine or is it my arch nemesis poison ivy? It features leaves of three (let it be!) and a hairy vine (no friend of mine!). Vote in the side bar.

Here are some sites to help you make up your mind: Missouri Department of Conservation and Wikipedia. And also this site about Clematis virginiana which is a poison ivy look-alike.

I've already picked up poison ivy from my yard once before and am no longer interested in any of that tomfoolery.
