That is Virginia Creeper - Parthenocissus quinquefolia.

Thank you so much. Using your info I went to http://www.wildflower.org/ and  saw photos in many colors (maybe the leaves were just turning color in the fall?) and some had bunches of fruit that looked like grapes! Thanks again.

Yes, that would be fall foliage color which be quite nice if the vines are exposed to sufficient sunlight. It is a prolific seeder, so beware of seedlings popping up in unwanted places.

I'm trying to propagate it through stem cuttings but have not gotten any to root yet. Getting some root stimulator from Amazon today!On the website I mentioned I found this:Warning: POISONOUS PARTS: Berries. Highly Toxic, May be Fatal if Eaten! Symptoms include nausea, abdominal pain, bloody vomiting and diarrhea, dilated pupils, headache, sweating, weak pulse, drowsiness, twitching of face. Toxic Principle: Oxalic acid and possibly others. (Poisonous Plants of N.C.) Also, the plants tissues contain raphides, which can irritate the skin of some people. It is far less likely to irritate, and less irritating Thanks again. Love your website! 

It should root very easily. It often roots naturally by ground layering, so you might try that.
