I've got a ton of poison in my yard and some of it has gotten me, so I am a tad gun-shy.  I'm pretty sure this isn't poison ivy but want to know if it is something to treat and remove carefully.  I don't see a way to post pictures so I will try to describe it...It has 5 elongated leaves, with serrated edges, growing on a woody vine.
 
 Thanks for your help
